First, machines normally only PXE boot if you press a specific key 
during the boot sequence.  Following the reboot after install, they'll 
just boot from the hard drive.

In case you find some crazy machine that behaves otherwise, you can set 
up your PXE config to boot from the hard drive unless you specifically 
choose a kickstart install.  Use a "default" PXE config like this:

prompt 1
timeout 600
display list.txt
default localboot

label localboot
         localboot 0

label rhel4
         kernel rhel4u3/vmlinuz
         append initrd=rhel4u3/initrd.img 
ks=nfs:installhost:/kickstart/server-rhelas4.conf ksdevice=eth0

... you'll need to fix that last line.  Everything after "append" should 
be on one line.

Yes, use the same ks=<URL> argument that you use in the PXE config.
