Mini-movie questions

Hi, all. I've been reading through the mini-movie icon tutorials (which are excellent, by the way; you guys are really helpful) but I had a few questions that I didn't see addressed in any of the tutorials. (And my apologies if they were addressed and I just missed them.)

First, what's the easiest way to achieve a border? I know you can use a template or border each frame one by one, but there's got to be an easier way to make a more customized base. Perhaps just by creating a bordered space on the base itself? And in that case, how would you do that in PS? I'm unfamiliar with basic PS processes, as I usually make my bases in another program and then just tart them up in PS.

Secondly, it's been suggested to make the animation first and then crop and resize so that all the frames are the same size to avoid any jiggling. If you do that, can you then make contrast and other color adjustments to the animated image that will affect all the frames?

And finally, what's the standard for capping and frame duration when working with people? I've seen every fourth frame and 1/24th of a second duration suggested; would you recommend those?

Thanks, guys. I figured I'd ask the questions I knew I'd run into before I started so that I don't get too hung up along the way when I finally try this out. :)
