What are considered the essential OT documentaries and extras, whether fan-made or official releases?

I have only seen Empire of Dreams + other 2004 material, From Star Wars to Jedi (ages ago) and the Holiday Special :(

I have heard of Jambe's documentaries, Deleted Magic, The Dr. Gonzo Extras and RowMan's discs, but I don't know much more than that they exist. What goodies do these contain and which are the best? Any others I've missed?

*WOW! Chuck Norris thread merge complete. Thanks Moth3r. Sorry for being a moron.*
