I can answer some of your questions as well.
There is no Ebon Hawk piloting mini-game, but the other mini-games have all been improved.
There are more faces to choose from, and there may be some choice of clothes and hight.
You will not be able to play as a non-force user this time. non-force NPCs each have a unique special ability this time (like Candrous' regeneration).
There are no new skills but there will be more use made of the old ones, including more workbench options. For example lightsabers now have 6 upgrade slots.
There won't be a rest option.
