I've now watched the first volume of Clone Wars. I figured I'd drop some ideas for you before I move on to Volume 2.

I think the first thing I would do is take the introduction of Asage Ventress and use it to open your film. It's required information for your climax, but it will slow the pacing of the film down if you try to intercut it with the battle for Munilist. I would open the film with Dooku attending the gladiatorial combat. If you did want to do some inter-cutting I would cut that segment at the point where Asage is being electrocuted. From there move to the battle. During the battle I'm sure you can find a good place to cut back to Asage waking up in Dooku's lair. That will aid in the feel that time has passed and also ad an air of mystery about her fate until we rejoin her, like a mini cliffhanger.

For the battle of munilist, I would do the following: First I would isolate the ground battle and the space battle. The ground battle can use some trimming as there's a lot of filler in there not necessary for a film. At that point I would begin putting the film together cutting between the ground and space battle. You want the audience to constantly remember that while things are happening on the ground they are also happening in space. With clever editing of the space battle it can easily be extended to match up better with the ground battle.

I'd drop Kit Fisto, Mace Windu and Yoda's rescue mission. They're all self contained stories which aren't necessary for the overall plot of the film.

Okay, those are just some initial thoughts. I'm going to go watch Volume 2 now and see what's happening there.
