Take a look at system-config-kickstart to help build your kickstart
files.

Anyway I think what you are looking for is,

# Clear the Master Boot Record
zerombr
# Partition clearing information
clearpart --all --initlabel

Copy the DVD put the ks.cfg file in the root of the DVD files

vi /<dvd-root>/isolinux/isolinux.cfg and edit the append line or add a
new entry like this

label yourlabel
  kernel vmlinuz
  append initrd=initrd.img ks=cdrom:/ks.cfg

Make iso and burn as described here:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/x8664-multi-
install-guide/s1-steps-install-cdrom.html

Boot DVD and type "yourlabel" to activate your kickstart file.
