1. I meant the trilogy, but it seems these three story lines are predominant in Jedi.
2. Ok, I get what you are saying about the Han and Jabba story. I think the thing that is holding me back from seeing the drama of the Han/Jabba story arc is that it is Vader who is instrumental in the capture. In a real sense, Jabba has nothing to do with it. Boba Fett and Jabba get Han by coincidence.
I am wondering if the involvement undermines this subplot? Jabba seems less threatening if he isn't pulling the strings.
