Marriage to a United States citizen conveys no status upon you. You continue to be in CPT status assuming you are maintaining said status. Otherwise, you are not in a valid nonimmigrant status. You may work on either work permit. You will be out of status if you drop out of school. You would not have a status at that point but you could advise the DMV that you are pending adjustment of status. You should take your EAD and all case related documents to the DMV.
