No kit is ever complete. Start with the bare essentials and add to it as the need arises.
You need a camera and a lens, something to keep the camera from moving (usually a tripod), something to trigger the lens (usually cable release), and focussing aids (dark cloth and loupe -- any cloth, sweathshirt, towel, etc. will work, and you can use any prime 50mm lens reversed as a loupe). Something to measure the light, film holder, you've got to get the film into the holder in the dark (changing bag, tent, or just a perfectly dark room) and someplace to put the film after you've exposed it (empty film boxes work well).
That will get you started, and your own experience will point you in the next direction.
