secure install

I'd like to have a secure install of some operating system on my laptop. I am not sure where to start. OS is not very important, I have either fBSD or gentoo in mind, even though I'm not so much of a power user. Truecrypt for disk encryption? Recently with the snowden craze there's been some information about securely browsing the web, even though this is not my primary concern.

SELinux.

Although it was made by NSA and probably has their backdoor in it.

Use SparrowOS on Symta.

stop using the internet if you're paranoid about being watched/tracked
