I have not listened to the radio dramas or shadows of the empire.
I'll look into Tales from Jabba's Palace, Bounty Hunter Wars, and the Sarlaac Adventure (with the beak?

I played through the Ep. III video game and there is a lot of pictures, cut scenes and stuff not in the movie in there. Sky Troopers with winged packs, Trooper Assissins (that can do matrix-like movement) and have blades on their elbows. There is a scene where Anakin impales the bitchy jedi librarian in the game (cool) oh and a turnabout scene where Anakin flips over Obi-Wan, impales him and kicks him down to the river of fire (styx?), he then has the emperor tell him "it is done, they will now rule the galaxy together", vade impales him and says he will rule the galaxy alone. Interesting. "Fliiping the script as they say".
