Truecrypt

I'd like to add Truecrypt to your list. You can encrypt whole drives, volumes, folders or just files. If you encrypt your drive, it needs a password to boot or read any of the data. Once it's booted, it's no longer safe though but you can do just files too.

Also about passwords, 8 characters is no longer enough. Have at least 12 and more if you can.

A really good password is "thiscouldbebetterbuti'lltakeitbecauseitworks". Computers have a hard time cracking language. A long sentence is more secure than a short random amount of letters and numbers.

KeePass is also good for passwords. http://keepass.info/
You can store your passwords (which needs to be encrypted and safe) or you can just generate good ones.
