I agree--if you got to the Underdark without too many problems, completing the rest of the game (without employing some type of cheese to keep your Drow items) shouldn't be much of a problem. But I, personally, would have no qualms about keeping my Drow gear as long as I didn't actually expose it to sunlight, because that's what is actually supposed to destroy adamantine, whether it's in the Underdark or not.
