Oh I forgot a most obvious ones (list #3), sorry about that:
30) Are Jedi allowed to marry and have children?
31) Do Sith use the title "Darth"?
For another inter-movie contradiction/inconsistency, compare the design and look of the Tantive IV in ROTS vs. in ANH. Also compare the incomplete "death star" in ROTS vs. the shape and design of the completed death star in ANH.
