So the research is on, full force. I'm going to whip out my extra UT3 DVD and see if there are any good tutorials on it, too.
I noticed in forums people were talking about controlling characters using paths, matinee, and kismet. So I think these should be some major searching topics to look into.
Here is a lower quality link of a tutorial featured on the DVD, regarding Matinee in UT3:

I've heard of Uscript and I'm still trying to figure out if it's now obsolete…
