Tapered pads (uneven wear across the pad) are not due to the rotors, they are caused by the caliper not sliding smoothly. It can be the pins (caliper slides) or where the caliper is mounted in the caliper holder. It can also be a problem in the piston (sticking) but that is less likely. What happens is that the caliper does not fully release, and continues to drag.

You can turn BMW rotors, as long as you don't go thinner than the spec. Trouble is, turning them brings them closer to the minimum, and they will wear during the life of the new pads, so even if they are OK when you turn them they can wear out of spec before the pads wear out.

The rear brake shoes are for the parking brake, they consist of a separate drum brake inside the rear rotor. Either that, or the mechanic was totally confused or the work order was written up incorrectly. The rear drum uses shoes, not pads.
