Shotokan too, from a student of Ronnie Colwell (google him, he's the most frightening man I've ever met but really nice too, serious but nice) I loved it and wish I could go back to it but I would only go back to it with my instructor and he lives too far from me now for it to be practical.
Any wetsuit will do for now as long as it isn't far too big or small, I won't be doing any great distance in the near future and I'll be getting my own soon enough.
