Your system seems to be trying to mix packages from RHEL 6.0, 6.2 and 6.3. This isn't going to work very well.
My first thought is that your yum caches are stale. Try cleaning them before you install the packages again:
Second, make sure you have set a Red Hat release for the system:
If you still can't get the packages installed, contact Red Hat. You have a subscription; you may as well get your money's worth from it!
