Hence I thought I would buy something to kill the lights out myself without annoying my shop all the time.

Codes and MIL's do not appear without a reason, and usually do not respond well to having money thrown at them randomly. Several of the codes you mention appear randomly when there is a low voltage excursion on the electrical system which tricks the DME into throwing "ghost" codes. If the car was in my shop, I would start by monitoring the charging system voltages when the car codes, or taking a look at the voltage drop across the heavy cables running from the battery to ground and the starter system. The low voltage issue and the heavy cable voltage drop is a well known problem with the 996 cars, Porsche even released a TSB about. I'm surprised your shop was not aware of it.
