This is pretty much a FAQ, but for the sake of completeness, here goes:

Unix systems have the conecpt of a user "home" directory. This is the
place where you start from when you log in. This is usually represented
by the character ~.

Applications have their configurations in "dot" files (the file names start
with a .) in the user home directory.

Global configuration information like passwords or system wide
configuration files go into /etc.

Normally, mail is stored in ~, but you may also find it being stored in
your mail spool directory (/var/mail or /var/spool/mail on Linux
systems, mostly).

In the case of RH, home directories are under /home, so as long as you
back that up, you should have most of your customisations. Keep in mind
that version changes can affect configuration files or directories,
particularly in the case of application suites like GNOME and KDE.

For most people though, backing up ~ and /var/spool/ should save system
state. A backup of /etc/ is advisable as well, _particularly_ /etc/X11.
If you are switching distros, you should recreate your users manually
(or script it using chpasswd(8)). Then after you have restored /home,
run 'chown -R user: /home/user/' as root, where user is to be
substituted by the appropriate user name.
