Here's how I see it:
Anakin/Vader: Wilder/slayer
i agree. Mostly because vader is actually more known for forcechoking people than for beating them to bits.
Palpetine: tainted psion telepath or wilder with a level of thrallherd
Thats Lord Sidious to you!
Luke: commoner/warmind since his education came later
fixed. the only way he could be useful, would be DM fiat, or templating that doesn't change his appearance.
Mace/Obi-Wan/Darth Maul: psi-warriors
