yum is still showing me 21 packages to update, all from an el5 repo.\
You can figure out what repo that is by "rpm -qi"ing one of the packages that is causing you trouble. Remove all offending packages, then remove the repo rpm (rpm -e rpmforge-release or epel-release or even another one, that is for you to figure out).
After you got rid of the offending packages and repo-release you can now install the correct repo-release for the OS version you are using and add the packages you just removed.
