I am encrypting my main drive right now with TrueCrypt.
You should do this, it does not take that long and makes you enter a password everytime you boot your computer. My friends computer was confiscated, by the police. They called him up because the could not get into, they asked for the password he just said he forgot. They ended up giving it back.
How to setup:

This is an anti key-logging tool, so if you do get keylogged all your passwords that you type in will show up scrambled on there side.
Very useful tool.
