I know I'm a tad late responding but this is what I do (because I'm
paranoid about my privacy):

I run Chkrootkit and rhunter though I use Chkrootkit more often.

I believe that is already built into the system.  Can't remember the
name of it but it checks, I think, for modified files.

I use Firestarter.  The real handy thing about it, other than being
very easy to use, is you can block (a) ports, (b) block protocols and
(c) use it for Internet Connection Sharing (ICS).

Encrypt each email. Gnupg works well.  For attachments, try bcrypt or
ccrypt.  Be aware of Google or any other web based mail service.  Read
the terms of service/conditions agreement.  You won't believe what
rights (explicit and implied) you either (a) give up or (b) waive.  It
is incredible and, in my opinion, morally wrong.

Not completely in anyway.  But you can make things harder for the bad
guys (which includes our not so illustrious government).

Do simple things first such as (a) turn off cookies, (b) set your
 browser history to zero and (c) block ads by modifying your "hosts"
file (/etc/hosts).  Here is an example of blocking

Cleans up a web page quite nicely.  I like it better than adblock or
whatever it is called.

You could set up an ICS system.  That way the ICS box automatically
blocks *all* not requested incoming signals.  Secondly, only the ICS
box has a routable (public) IP address, while the machine you actually
use has a non-routable (private) IP address.  By installing Firestarter
on the ICS box you can block ports and protocols *before* your machine.
Plus you can have your own home network.

If you really want to clean up the signaling then consider isolated
ground electrical circuits (using thhn stranded wire) in the room where
the computers are along with metal grounded screening between the wall
studs and inner wall and/or ceiling (normally drywall).  You would be
amazed how 'dirty' the air (with electrical signals) actually is within
a home.

No idea.
