I think on the 4e thing, if it fell closer to Star Wars Saga Edition than it did it would have groked better.
In the first set of things I had trouble groking was AC vs Reflex Defense. Saga Edition had a similar set up to defenses rather than saves but they cut AC with Reflex Defense applying to standard attacks.
Also classes having a much shorter list of abilities, and groupings of those abilities into archetypes so that you could get a sense of what your characters range was helped alot.
