The bundle should have everything you need to start shooting. If you're camera's filter threads are bigger or smaller than 72mm you'll need a step-up/down ring, but I think Dennis Wood supplies those with your order. If you're going to be using long, heavy lenses and/or you're putting it on a camera with small filter threads like the HV20 then it might be a good idea to get some rails for support.
What type of Zeiss lenses do you plan on using? If it's the Nikon one's then yes (just get the Nikon mount). If you're talking about the PL mount Zeiss lenses then you'll have to get the PL mount to use them.
