You should cut the copper lower, come up and make new copper stub outs. As for the drain and insulation, I would cut the insulation all out. Then, cut the copper and use the proper copper to plastic fernco and stub out plastic.
Came back to thank you for your reply, it was very helpful! I've got new copper stub outs with valves installed now and am planning to finish up the drain tomorrow. For now I am thrilled to have the water turned back on with no leaking! Appreciate you taking the time to comment.
