I agree mostly with what Hardcore Legend and MeBeJedi said. I dont think there were any problems with the Taun Tauns at all. They used an animal native to Hoth to travel on before they got the Speeders to work in the cold? The lizard imo, moved awkwardly, had an annoying squeal every five minutes (if not more). and had too much focus on it, it was like super lizard.

as far as the Leia having memories of her mother, i agree that Padme should have lived for a few years after her delivery of the twins, even if they were split up right away. Leia is sensative to the force so the force related memories do work, plus its more likely Bail would give Leia info on her real mother than it is that Owen would give any information to Luke about his real parents. Plus, maybe Leia just has that Mother/Daughter connection and Luke has a Father/Son. I mean, Vader couldnt tell that Leia was his daugher until after he found out from Luke. Also Luke could sense Vader's presence whereas Leia wasnt able to. Just an idea.

and yeah, the whole your father wanted you to have this shouldnt even be an issue. I mean, once you find out that Vader was Lukes father in ESB, it should be obvious that Anakin never actually said, here, give this to my son when he's old enough and that it was just Obi-Wan protecting Luke from the truth (think of all the possiblities of what could have happened if luke found out Vader was his father at that point in time) and Obi-Wan also presenting the saber to Luke in a formal way.
