I am able to kickstart servers with the default install files that were on the original DVD media. However I want to be able to update some of the rpms with newer ones like a newer kernel. I also need to add one or two custom rpms of my own.

I am pretty sure I need to update the repo files that tell the system what rpms are available. I installed the createrepo rpm along with some other dependencies required but I have not been able to find any definite directions on how to accomplish this.

The usual approach is to set up a separate local archive, and 
to run 'createrepo' to build the files 'yum' needs, and to 
handle it in %post

but it is perfectly possible to dump new (later NEVR) packages 
into a local image of an archive and to run 'createrepo' on 
that directory --- RPM and anaconda, and in recent RHEL, yum 
will pick up the change

That said, there is (or at least was, I have not verified this 
is still present for a while -- doco indicates it is still 
there, but anaconda doco is notoriously bad) the ability to 
add a './RHupdates/' directory to hold such a package 
repository that anaconda will 'automatically find'

all that said, it is easier usually in the ks.cfg %post 
stanza, to:

a) use a 'HERE' document to drop the local repostitory 
specification into /etc/yum.repos.d/  and then

b) run
 	yum -y --enablerepo=(localrepo) update
 	yum clean all
