SWTOR: Defeating Baras (Light Side)

To be honest Baras kicked my ass a couple of times. He has a one hit kill move that you have to interrupt. I didn't know that the first time and died, and the second time I almost killed him, but but I hit some kind of problem that had me suspended in the air for no reason and couldn't interrupt him. The third time I pretty much destroyed him. Please ignore my messy skill bar.
