Palm Tree of Doom,I don't think there are the effects you mentioned available for downloading anywhere.
When I was using Movie Maker,I have downloaded some effects from Rehan in this site:
http://rehanfx.com/
If you want,check them out.But they are pretty simple and not something that good editing programs offer.After all,Rehan hasn't updated this page for ages.
The other way is to create the effects and transitions all by yourself using the program mentioned in Movie Maker Forums(the link by CrackThe Sky) and writing the codes for everything you want.This page should be useful then:

But personally,if you want to make amvs with good effects and filters,try moving to Vegas or Premiere.
