What KOP pieces from last year can we not use?

Usually there are restrictions as to which motors you can use. For example if there are any motors in past years which are not identical to the motors provided in this year's KOP, you can't use them. We had to bust several robots last year in inspection because people recycled illegal motors.

As for other parts, why not read the manual? Usually they restrict which parts you're allowed to use from previous KOPs. If something isn't mentioned then it's probably fair game. Read the entire manual before making assumptions though!
