If your lights are like mine, a 12 inch diameter reflector or thereabouts,
I'd recommend 4 lights instead of two. For something that large I don't
believe two will provide even illumination. A bright overcast day will
certainly do the trick.
As for film, the Kodak T-Max B&W films are easily processed commercially.
If you have a pro photo lab handy, nothing will beat Tech Pan for sharpness
and lack of grain, but development is not readily available in many areas.
I think I try a normal lens in the 85mm-135mm range first and see how well
it worked. For such a large object you are well out of the need for a macro
lens. However, a macro will certainly work; I just don't see a compelling
need.
Good luck :)
