3. I would recommend you get a GRsecurity kernel and sit tight on RH9. FedoraLegacy has updates for RH9 by the way so make it a habit to update from them. A firewall machine with no LAMP (Apache MySQL and PHP) is harder to exploit and grsecurity locks down things well.
Be sure to subscribe to the -legacy mailing list and help test packages. A lot of stuff is sitting in the hopper awaiting testing. If it doesn't get tested, it doesn't get released. See the list archives over the last couple of weeks for details.
