Haya and Greenlaw- Yep, that was it. When you're learning, you do stuff you don't know NOT to do, and apparently I threw a keyframe on EVERYTHING at frame 1, including Bone Reparenting. Couldn't see what I did because all the timeline layers were consolidated, but when I unchecked that in preferences, my timeline exploded vertically! I quickly realized I didn't need almost all of it, so now everything looks like the tutorials again.
PLUS I got my animation to cycle! I'd put a keyframe right before the one where it repeats (if frames 1 and 25 are the same, I added one at 24), but somehow it didn't apply itself to all the bones so the cycling wasn't happening. I told it to repeat from 25, where everything had a keyframe and it started right up.
And anyone snickering at my faltering first steps in this wacky program should challenge me on my Flash skills.

I know how to do neat stuff, just not in this thing yet.
Thanks again, guys!
