We just got a new server with Red Hat Enterprise Linux 5 pre-installed.
 Cool!  Red Hat sells an "Application Stack" which includes JBoss (don't
need) and the usual LAMP stack.  Cool!  The Application Stack costs,
minimum $1,999 for a one year subscription and download installation.
NOT COOL!  The boss would choke on that budget request.

I want to keep this system updated and install needed software in as
automated a fashion as possible.  Are there well maintained, no cost,
community repositories for RHEL that I can point to for installation of
software via yum or another such tool?

I'm looking (not too hard) but have not found such connections yet.
