Chances are that running 'rpm -vv --rebuilddb' the second time,
without rebooting, would work too.  I have seen that in the past.
No harm in rebooting. :-)

You may want to run at this stage 'rpm -qa --last >packlist' and
check results to see what "old" packages still linger on your system
and if you want to keep them.  Also if 'yum-utils' package is
available in 'extras' for your OS version then it has a utility called
'package-cleanup'.  Options '--problems' and '--orphans' would be of
a particular interest.
