I don't have much to add about the RP for op, but I would like to expand slightly on what was said about BH. Specifically, the "Bounty Hunter's Creed", if you decide to take that route:
-No bounty is worth dying for.
-People don't have bounties. Only acquisitions have bounties.
-Capture by design, kill by necessity.
-No hunter shall slay another hunter.
-No hunter shall interfere in another's hunt.
-In the hunt one captures or kills, never both.
-No hunter shall refuse aid to another hunter.
Also note that class =/= role, most of the time. For example, if your character's official class is Jedi Knight, but you RP closer to the typical Sith Code, you could be considered a Dark Jedi. Conversely, you could be a Sith Lord who goes against the ideal/stereotype that hate and rage are the the only 'true' Sith ways - passion can take many forms, after all. Regardless of what you do, be sure to do research if necessary, and stick with the personality you make - it's usually not very acceptable to have a flip floppy personality when you're in-character (IC).
These are merely suggestions. I don't have much Star Wars RP experience, but I do observe a lot, so take this how you will.
