You can gain DS points and influence Bao-dur by killing the Czerka salvager in the underground base at Telos and at N.S. by force persuading the two muggers to jump into the pit. Handmaiden you can leave her on ship and fight her at level 10,14, and 18. Don't remember whether you need more influence or not. I turned Handmaiden, Atton, and Bao-dur into Sith as I recall. By end of game they were all tending Dark and Visas had virtual mastery. We glowed bright red at each other.
