Your key is on top (triple tree) or side (below fuel tank)? The former will be Gen 2 while the latter is Gen 1.
You will be spoilt for choice on footpegs. Can either use the conventional peg or board. You can also mod it to become a forward control, if you don't like the "squatting" stock style. Or you can even mod it backwards, shorten the risers and make it a cafe racer.
But you've already decided - chopper. And almost the easiest option since Phantom has already most parts looking like a chopper.
Still the same warning i give to everyone going to Aunty-shop : Don't judge a book by its cover and do your research first before deciding. Read my post about my shopping experience to see how you can make your modding trip a more pleasurable one.
