Boot from CD

Choose upgrade...it will only install updated stuff and add only
dependencies.

Redhat also offers their up2date service - 1 machine free per account.
On any machine connected to the internet, merely configure and run
up2date -u and it will install updated rpm's for that which is already
installed and has been updated. Works fine and it probably all you
really want.
