I don't see how the addition of the Falcon taking off hurts the pacing but in every other aspect of what you say I agree with you.
It interrupts an originally perfectly edited and scored action sequence. Williams score is another thing that constantly takes a hit with his mindless re-editing, not only in the obvious ways like in the Falcon takeoff, but the way Williams wrote the score is definitely not how he would've written it if the film had the editing of the SE.
