This system is not registered with RHN.

RHEL needs to be registered with Red Hat in order to function to its full extent. If you're going to use the CentOS repos anyway, you should look to installing CentOS.

Yes, I second that.

While centos is a redhat clone, there are some subtle differences in packages.
So updating might eventually not work as expected.

And as you intend to use centos repos anyway, there is absolutely no reason to not install centos in the first place.

You have to configure yum. Did you configure yum on centOS?
To configure yum there are several steps availble first configure it then it will work

Any reason you are using CentOS packages? RHEL has a wonderful package list and system. If you want to use RHEL for free by getting CentOS repos, just use CentOS. I prefer RHEL because of the support and updates, but CentOS is very similar;

As per process RHEL needs to update only from RHEL repository , While you can configure your YUM /etc/yum.d/ directory , to disable in accessing the RHEL repository and configure to access the CENTOS repository instead, This is doable
You can remove the repo-name of the RHEL
and
Download and Install RPMFUSION for your centos

But it would be better to stick on to the pre defined process
