Boards such as the the Replica Prop Forum http://www.therpf.com/ and the Replica Prop Board http://theukpropparty.yuku.com/ have guys making Studio Quality Miniatures of Star Wars models and Costumes etc... that would be perfect for some of the shots, there are even Stop Motion Replicas of the Taun Taun and the AT-ST getting built.

Never been there myself, but I hear the guys over at the Replica Prop Forum are cool, and they're definitely sticklers about accuracy. (Adam Savage from Mythbusters frequents those forums if I'm not mistaken, as well.) I'm sure if you ask around there, they'll be willing to help you out in any way they can, Ady, especially if they're familiar with the Revisited project!
