Im guessing I just use my BTC address that bitcoin gave me.
Truecrpyt it and backup my wallet on flashdrive? gotta be safe here

That, or use some online wallet service. I personally found the advice in the securing your wallet sticky to be most helpful. I use my daily wallet for small things, donations, etc, and my secure offline wallet for big deposits.
At this point I'm too broke to really benefit from the secure wallet, but it's there haha.
