OK, I'll try that tonight. This has been an interesting process. I'm learning a lot about what not to do when updating a system, that's certain.
Doing a bit of googling, I found that I'm not the first to have this problem. It seems that it is probably cause by either 1) the repodata not yet being updated across mirrors or 2) Incomplete or garbled data in the cache. It was suggested that: yum clean all or yum clean packages may take care of it. It was also suggested that gpgcheck be disabled, though that doesn't seem like a good idea.
It was also suggested that just waiting it out will work. Hmmm...
Some days it seems like a coin toss between George Orwell and Monty Python...
