I'm Nervous

I'm about to upgrade my blog software and my theme.  I have to do it during nap time or it will never get done.  I have no idea if I've backed up properly, or what this will do to my blog.  I've been reading and trying to prepare for this for about 3 weeks and, really, I just can't figure out how to do it, so I'm just going to try it.  In the middle of the day, no less.  Sometimes you just have to say, WTF.

Update:  Just a half hour later, I think I'm done.  Let me know if you find any buggies.
