1: Well, the only thing a Noble can really offer a melee build is the Fencing Talent Tree from the KoTOR Campagin Guide. Though those talents lean on CHA, which you take a penalty to. Depends how exactly you build it. Assuming you plan on exploting your natural SF(Deception) and feinting a lot, Scoundrel could get you either Sneak Attack or Dastardly Strike to nicely complement it.

2: Speaking of KoTOR, check out the Melee Duelist. It is one of the few ways to make full attacking with melee work. And since you have your copy of KoTOR out, you might like to know that you can qualify for Elite Trooper with Flurry instead of Point Blank Shot.
