there is a %post section in your kickstart file that can do most of these 
things. It runs as a bash script, chrooted into your new / filesystem, before 
your sytem is rebooted.
eg
%post
useradd bob
echo "insecure" | passwd --stdin bob

rpm -Fvh ftp://server/pub/updates/*.rpm

rhnreg_ks --activationkey=....

you could conceivably set up the print queues in a similar way
