There is a "downgrade" feature of yum, as in 'yum downgrade cups', and 
later you may find the --exclude feature useful.  And there are files 
README and yum.cron.excludes in /etc/yum.d/.  Since I've never used these 
features, you may need more detailed advice from others.  There's also a 
"remove" feature of yum, as in 'yum remove cups'.  You can then take a 
downloaded earlier version of cups (and probably other rpms reported as 
removed) and install them with 'rpm -i [list of .rpm files]'.
