I am about to buy the Wii Fit Plus

Do I need to buy a motion sensor to attach to my wii remote in order to be able to use wii fit plus? Do I need the boxing gloves? I am a new to wii and just ordered the console and wii fit plus bundle. I know the wii console includes 1 remote and 1 nunchuck. I am going to order 1 additional remote and nunchuck so that 2 of us can play at the same time. Just need to know if I need anything else before I can get the games to play them correctly (at this point we're just getting the 5 sports and the wii fit plus). Any advice you can give me is greatly appreciated. I plan on getting the toy story mania game eventually...do I need motion sensors for that game?
