Just watching that clip I would say to cut down as many of the 3P0 scenes, especially before they get captured by the Ewoks (as they just come across as unnecessarily annoying, much less would give them away pretty easily).

I would probably cut out the scene with the trooper shooting and (ugh) "attempting" to capture Leia. Jesus Christ, he has the first and SECOND shot and she can't even see him, and then he walks up behind her and says Freeze?!? If he wanted to kill her to begin with, why do that? You (or any editor) could just as easily edit that scene to end with Leia following Wicket back to his camp.
