"Nikon F2 Photomic and a 55mm f/2.8 Micro-Nikkor(I'm aware that it's an odd choice for your only lens"

A combination I use a lot. You could do a lot worse - one of the best 35mm cameras and lenses ever IMHO.

If your Micro-Nikkor came with an extension tube, see if you can get your hands on an old 200mm F4 Nikkor-Q - they're usually pretty cheap -- and try that with and without the tube. Lots of fun.
