Instead of these, the issue should be presentation. I don't care if the rebel medical friggin' frigate had a supply of prosthetic hands or whether it can make them from scratch in a few minutes. Or it shouldn't matter if they had a Sith suit lying around for Anakin (I suppose one could argue that they made Anakin to fit the suit, rather than claiming they had a suit in his size). The slow optical wipe from the escape at Bespin to the rebel fleet gives the audience a clue that enough time has passed for everyone to heal and catch their breath. In ROTS, Lucas needed to set the stage for the next 20 years between the Episodes III and IV, but who knows what the heck he was doing, so we get a very rushed end of the movie. All the things that the fans had been waiting to see were crammed into the last 10 minutes. No wonder the believability is shot to hell.
