Ok, so I was listening to a replay of Lorne Peterson's presentation on the book at ComiCon and here's the condensed version of the story about the speeder.
The speeder is actually a replica of a tiny one that was made for episode iv that was used in the scene where the tuskens take aim as Luke and 3po are looking for R2. He said since it was so small and shot at a distance that a lot of work did not go into it. In fact the engines were made from sharpie caps. He always like that model and it was given away so he rebuilt it (with sharpie caps) and thought it would be cool to include it with the figures. Everyone likes things to be "screen accurate" so there you are. One that's as crappy as the original.
As for the panels, well those are just crap.
