There's a new thread just for helping you get through KOTOR: http://www.bobafett.com/boards/viewtopic.php?id=2407 would be best to post further questions there.
But to answer you question here, pazzak is purly a side quest to gain *or lose * money, and the dancing girl is only a way of earnining lightside or darkside points. Go lightside by freeing her back to her BF, or go darkside to keep her *check in with her once and a while to get your cut of her earnings*
It's a long, drawn out prosess getting of Telos Station. You need to start by either working for the Ithorians or Czerka Corp. Complete missions for one or the other of them for a while. Czerka is dark side for the most part, and the Ithorians are light, but there's wiggle room to do either on both jobs.
Hope this helps
