For the meter to work, you need a SR-44 silver-oxide battery.
A good monochrome film to start out with is Ilford HP5 or Kodak Tri-X. They are both ISO 400/27° (or in the old nomenclature ASA 400, 27 DIN). They are quite forgiving when it comes to getting something usable, even if the technique isn't there yet. Colour depends on what you can get locally, it will take any 35 mm film in the 135 format.
The lenses need to have the rabbit-ears that were standard on all manual focus F-mount lenses. AF-lenses will mount, but they won't couple to the meter. G-type lenses without an aperture control ring aren't usable at all as there is no way to control the aperture. I have a blog post up here about what Nikkors were exceptional optically.
