Answer 1

I assume you mean RHEL-5, at which point you probably have the "yum-rhn-plugin" package installed ... which will give you access to the RHEL repositories as soon as you register with RHN (rhn_register).

You can also put files into /etc/yum.repos.d as "normal", Eg. for access to the EPEL repo.
