Jesus Christ...

If you have a P0300, start there. You may also want to state the miles you have on it too. Given that you have a P012B that could indicate supercharger issues as well. No way to really know until you get started taking it apart.

If your plugs appear wet then you have a bad direct injector or several. This could get ugly really fast. If that appears okay then I would pull the blower belt off and manually spin the supercharger pulley by hand. If you hear anything other then the normal sound of the rotors turning (the crushing sound or marbles in a can that you hear when you try to give it gas) then you got bad supercharger internal bearings. It may require a rebuild or in some really bad cases, a whole new supercharger unit.

If you need injectors I got some OEM take offs from my own car that were in stellar condition prior to being pulled off. I upgraded and went larger. I'll try to help out however I can, but like I said this could get ugly REALLY fast given that that crushing sound you are hearing when you give it gas is concerning.
