Answer #4
if you are wanting to make an animation video clip with sound i would make it in flash, then export it as a video.
open movie maker and use the text at the start of the clip, but you could do all of this in flash and it would be easier.
Answer #5
if you already have the animation, then use Camtasia to add audio, edit etc
