48 hours mining and still no payout from P2Pool? Am I doing something wrong?

So I am brand new to BTC mining, this is my first attempt. I recently purchased three Bitmain U1 antminers to mine on my home PC. After installing drivers, using correct version of CGminer, and picking a pool (I had read about GHash.io being able to 51% and thought it better for the future of BTC if I didn't give it any more power), I was ready to go.
I first started a little bit over 48 hours ago, mined for a few hours before my computer went to sleep on me and I had to restart. So I now have been mining 36 hours straight. I haven't received any payout from P2Pool even though there has been several payouts while I have been mining.
Is there a minimum payout for P2Pool? I know whatever I mined can't have been that much, with only about 4.6 GH/s hashing power.
Or am I doing something wrong? I don't know how to write the commands for CGminer in notepad, so every time I restart CGminer, I have to input everything including my bitcoin address (username) manually.
I use multibit, do I need to use bitcoin.qt?

GPG instructions and public key list for verifying Bitcoin clients.

I have noticed their is a growing problem of fake bitcoin clients, and I expect the frequency and elaboratness of these fake clients to increase.
Verifying the signatures for these clients will detect if you are receiving anything other than what the signer the of the software signed. The exception to this is if the attacker acquires the signer's private key, which should be a lot more difficult than tricking users to visit the wrong site or hacking servers. This can also be addressed by using multiple signatures per client.
An important part of this process is acquiring the public keys for the sofware signers in a secure manner.
To help with this I have included a signed list of fingerprints and where to acquire the public keys to act as another source to verify the keys used to sign bitcoin clients.
I have also included instructions for verifying the fingerprint list and bitcoin clients.
To deal with the issue that posts and comments on Reddit can be easily modified I suggest other users (especially well known ones) post a signature of the fingerprint list in a comment in this thread, or at least a hash of the fingerprint list (not as secure but still better than nothing).

Verifying the fingerprint list:
Save fingerprint list, from the first plus to the last plus, to a text file called fingerprints.txt
Next save my key to a file called dcc4e.asc and my signature to a file called fingerprints.txt.asc
In terminal or command line run:
gpg --import dcc4e.asc gpg --verify fingerprints.txt.asc 
You should see:
Good signature from "dcc4e " 
GPG examples for verifying Bitcoin clients:
Verifying Bitcoin-Qt:
First download, import and check Gavin's key:
Download his key at bitcoin.org/gavinandresen.asc
In terminal or command line run:
gpg --import gavinandresen.asc gpg --fingerprint 
Check that the fingerprint for Gavin's key matches 01CD F462 7A3B 88AA E4A5 71C8 7588 242F BE38 D3A8.
Then download the wallet software and signature.
Verify the signature:
gpg --verify SHA256SUMS.asc 
You should see:
gpg: Good signature from "Gavin Andresen (CODE SIGNING KEY) " 
The signature for Bitcoin-Qt signs the hash values. So we must compute the hash of the specific downloaded software manually. This example is using the linux version.
gpg --print-md SHA256 bitcoin-0.8.6-linux.tar.gz 
Check that the output matches the associated hash value in SHA256SUMS.asc
Verifying Electrum:
First download, import and check ThomasV's key:
This key can be found at a keyserver.
gpg --keyserver pool.sks-keyservers.net --recv-keys 7F9470E6 gpg --fingerprint 
Check the fingerprint.
Download Electrum and the signature.
Verify the signature:
gpg --verify Electrum-1.9.6.zip.asc 
You should see:
gpg: Good signature from "ThomasV " 
For this example you do not need to manually compute any hash values because the signature is signing the downloaded file directly instead of signing a list of hashes.

Just starting with Bitcoin. Need insight.

Hey. I just created a Bitcoin wallet. As a Mac user, I installed the Bitcoin-Qt and the MultiBit program. Honestly I don't know the difference between them. Beside that already have an account at blockchain and Kraken. My question is, where to start? I read that mining ATM does not worth it, that's why I took a look at Kraken to trade and invest. I don't understand what the Bitcoin address at blockchain is, or how do I use it at the bitcoin-qt. So basically I'm lost. Any online manual or general explanation would be great. Thank you

Sending and receiving Mastercoins for the novice

I'm hoping someone will be able to assist a novice with some basic questions regarding sending and receiving Mastercoins. My questions:
1) To send MSC I want to use JR's Mastercoin Advisor. What is the "data address"?
(i) Is the "data address" a new, unique address generated by the Advisor for each transaction according to what you input?
(ii) Does the unique address include the information on what is sent (TMSC or MSC) and the amount sent so that this does not have to be specified when sending the transaction from the Bitcoin-QT client -- i.e., that information - amount and type -- is included in the data address?
2) Once you have the data address, is that all you need from the Advisor? I.E., you set up a transaction manually on Bitcoin-QT, sending 3x 0.00006 BTC to each address - Exodus, MSC recipient and Data addresses?
3) Is a miner's fee required? If so, is it 0.0001 BTC? To which address do you add the miner's fee?
4) Are MSCs sent the same way as BTCs? Bitcoin-QT send the entire amount of your MSCs from the address holding the MSCs and then sends back the change to a different address in your wallet? So if I have 1000 MSC on the address and send 100 to the recipient, I receive 900 back at a different address in my wallet with a different private key? Or are they sent back to the same address? How will I know which address the change is received at?
5) When sending Mastercoins from the address holding the MSC, do I need to have sufficient Bitcoins at the same address? In other words, I need to co-mingle BTCs and MSCs in the same address? How does the wallet tell them apart?
6) Finally, if I received the MSCs from the Exodus Address in a Bitcoin client that does not support sending to multiple addresses (in this case Multibit) can I simply import the compressed private key to the Bitcoin-QT client to perform the transaction? Are there any concerns about having the same data in two clients?
That's a lot of questions. If anyone can answer any of them (you don't have to tackle them all :) if that too much trouble, I'd really appreciate it.
Many thanks.

Anyone got a private get entered manually into Bitcoin-QT recently?

Recently I got Bitcoin-QT up and synched with the network, yay! Then I went to the ATM and bought some bitcoin, yay!
Then I tried several times to enter my Robocoin generated Private key into Bitcoin-QT, via this way:
https://en.bitcoin.it/wiki/How_to_import_private_keys_v7%2B
I'm pretty darn sure I typed it out correctly. But I still got "Invalid Private Key (code -5)". :(
Has anyone else used the Robocoin ATM and entered the Private key manually this way? I'd rather not use a 3rd party service, you know? Keep it all kosher, as it were.
What am I doing wrong? Are blockchain.info and/or multibit.org really just fine? Am I missing a step?
I'll totally come back and mock myself if I entered the key incorrectly.
EDIT Yup, I'm an idiot. Totally typed it in wrong. Nice. I've always felt like the special kid in the computer class. I kind get most stuff, but there's plenty of Trons ahead of me. I like it, it's fun, but the thickness of my skull contributes to a smaller cranium overall. Not quite a cephalic baby's Thalomide nightmare, but damn I'm dense sometimes. Ugh. Le Ugh. Dummy dummy dummy.
