Yep, After Effects sure is fuckin sweet! I've never done frame-by-frame animaiton in it, I'm guessing it's not too good for that.
You're gonna have to just experiment with different ways of exporting the video to get the filesize down. I can get a minute-long 640x480 video down to like 10mb as a .wmv, but I'm not a super experienced video person.
I think you could still learn a whole lot about animating things in a way that looks good and fluid, by the way.

Pretty cool, the camera sweeps are certainly better in After Effects.
