Security on many systems is what you make of it. For example, the Ramen
Worm (which attacks Red Hat Linux systems) uses old well known
exploits. Any person who keeps a well patched system should never have
had an issue with this.
In contrast, Microsoft systems do not have the patches availabe in such
good time to prevent such being a problem.
There are very few linux virii, and general awareness can thwart them
(don't surf the net as root etc).

Safer. Just remember to keep up with the patches! (this applies to any OS

Not sure. Personally if you're that paranoid, don't connect to the
internet. And an encrypted filesystem is going to really stuff your
system performance in a major way.

Browsing: None really. All sites are not https. you can turn off
Email: pgp (or gpg) encrypt your mail. Only worth doing if you have
someting worth encryping like passwords/bank details.
IRC: I'm not aware of any SSL type secure addons to IRC.
BTW, if you're even marginally paranoid, use ssh/scp in preference to
telnet/ftp. Telnet and ftp both send plaintext passwords.

Yes indeed it will.
