Hardcore! What lenses and lights to use for Comic-Con photography and dance taping, all dry!

Regarding lenses, in addition to focal length, there are bokeh considerations, for example, 1.4 bokeh is definitely better than 1.8.
Regarding fill light, there are many one-light masters out there as well, though obviously dual and triple lights are more suitable for novice beginners. But for one-light photography, dual-light is a much more portable and manageable combination.
On a final note, ambient light is your extra light.
