Install the bitcoin-qt wallet, send the coins from the pool to yourself once your wallet is working.
Encrypt the wallet with a very long pass-phrase, like "she sells bitcoins at the seashore plox please diet pizza" it doesn't really matter exactly what it is as long as it's something you can remember, it's sufficiently long, the words are at least partially random, and it helps a lot if at least one word is a made up word not in a dictionary. If you must, write it on a piece of paper and store it in a safe, but never ever use the same paraphrase anywhere online and never type it into your computer unless you are actually moving your bitcoins, and even then make sure you scan extra well to be sure you have no keyloggers.
Then you shut down bitcoin-qt, go into your appdata/roaming/bitcoin folder and copy wallet.dat into dropbox, microsoft skydrive, or google drive or better yet, all three. And keep a local backup too.
Or you can use a paper wallet, but there are potential risks involved in the printer storing the image and such. My above method is pretty safe.
