All of Obi-Wan's inconsistent dialogue about Uncle Owen is out.
I'll be working on the duel next. So far, my ideas for it have been very much along the lines of what you just posted, with a few exceptions in the choice of music cues, you'll see what I mean when you watch the clip. I've found that "Anakin vs. Obi-Wan" from ROTS by itself adds a new dynamic to the entire sequence, from Han running through the blast door, all the way to the Falcon's escape from the Death Star's landing bay. I would definitely like to see this clip you have though, as I might be persuaded to change my mind.
Jabba and Boba Fett are certainly out. I hope MTH agrees with that one too.
A lot of the technical work, like intricate effects shots, the Ponda Baba thing, and things like rotoscoping lightsabers and so forth is somewhat beyond my capacity at this point. I agree they need to be changed. But, maybe it would be possible to outsource the work on those particular shots to a willing person who is a little more experienced in that area of expertise.
EDIT:
OKAY, IF YOU'RE GOING TO HAVE OBI-WAN TELL LUKE THE TRUTH IN ANH THEN HOW ARE YOU GOING TO CHANGE VADER'S REVOLATION TO LUKE IN ESB ???
We haven't discussed it in too much detail yet, but it might be something to the effect of "No, OBI-WAN killed your father." But, it hasn't been decided yet. We might cut it so there's no revelation at all. There won't really be a need for any revelation. Luke is defeated and cornered. Vader tries to convert him to the Dark Side. Luke chooses suicide. There is no ROTJ.
Kidding.

But, don't worry. It'll be good, whatever it is. I'd actually like to pass the ball to MTHaslett on that question, as I think he's the one with the whole grand scheme in his head for that particular part of the story.
