Just went to a tourny today, and I was wondering. There was a guy there that Tractor Beamed me. He picked the maneuver and chose which side to roll. Don't I get to pick all that?

No, he was right. If you get tractor beamed, than your opponent gets to pick.

Yeah, the other guy picks the barrel roll direction and the final position of the ship. Keep in mind that he can only move a particular ship like this once per round as any other successful tractor beam hits will only reduce your ship's agility value by 1.
