I would be sure to get the three Christmas themed swf movies that were made available at the official site several years ago. There was "Holiday At The Fetts," one with the Wampa, and one with Geonosis as a toy factory.
A few others I've found online that I like include:
-- Rob Stangroom's "The Jedi Song" music video
-- Weird Al's "I Think I'm A Clone Now" fan made music video (with clone troopers)
-- Bentframe's "Star Wars Gangsta Rap" music video
-- "The Bounty Hunters Talk Back" - interviews with the Bounty Hunters from the classic trilogy
-- "Star Wars Toys That Never Were" - funny toy proposals
