Okz. And are you talking about Naga Sadow? Or is he on another planet....ah screw it. We can do the telekinesis part first and then go to the tombs for a bit of lightsaber training.
Areas for training'd be good. I have one idea about this spot Dawn uses up on a plateau by the Academy. at least I think Korriban has plateaus. who knows. And the roof of the Academy as well for its seclusion and vantage point. But...meh...I really have no clue what the layout of Korriban and the Academy look like, obviously.
As for important locations the only one's I'd know of would be the Archive and the Valley of the Sith Lords or whatever it's called. If you know of any other interesting places that would be quite helpful XD.
