For example, in the previous comment it was mentioned to replace '$release' with '5.4' .... however, should the box move from '5.4' to '5.6' EUS yum would be 'broken' or atleast, pointing to the wrong repo.

Well - not in rhel5 but in the fedoras and rhel6 you can
use /etc/yum/vars/somefilename

fill the file with whatever single line you want
and then yum will expand that into $somefilename in your config files
and .repo files
