i doubt you need to recompile the kernel.  if you are using a
non-enterprise/server edition of RH, ipchains is compiled as a kernel
module.  i really can't remember the last time i needed to re-compile
a RH kernel to get a non-esoteric piece of functionality working.

three things come to mind:
1) read the ipchains HOWTO.
2) edit /etc/sysconfig/ipchains to your liking.  this will be time-consuming,
  so i suggest you look hard for sample firewall configurations to get you
3) "chkconfig --add ipchains" will add ipchains to the start-up sequence.
  w/o rebooting, you can use "service ipchains start" to start it, and it
  will take care of loading the kernel module and starting ipchains w/the
  rules you configured.
