Definitely looks like the pads have worn down to the metal. All you need to do to check is to take the wheel off, turn the steering to full lock and look at the pad through the gap in the caliper. You would normally be able to see how much material is left on the pad, although I would guess that you won't find much!!
If I were you, I'd replace pads and rotors with new and not bother getting the rotors skimmed as they have taken a fair beating, judging by the pic.
