I cut the asteroids entirely on my first run through. I have them chasing the falcon and then them dissappearing onto the back right away. Then they float away with the garbage and find that Bespin is near. Then I put in a couple of the Han Leia scenes that are actually in the cave. While they are presumably floating toward Bespin.
What I really want to do is figure out a way to make it appear that they got Frozen Han back from Fett before its over. Because I plan to cut the guts out of Return of the Jedi
