Make sure you have backed up anything else valuable (you have already separate
/home partition).

Have you analyzed preupgrade related logs in /var/log/ ?
But do not spend too much time on this.

Have any distro cd/dvd handy in case you have to get back to your system !

man yum
You can start an upgrade/cleanup process like this:
# yum distro-sync

Tell us the result of it - we really want to know !
