Here is a test I did a few years ago. This particular example was never finalized, so there is still some slipping on the feet. Most tracks seem to work 80-90% straight away, and that last 10% takes the real work.

For lighting, I photograph a mirrored ball in the same environment. I usually take 12 exposures and create an HDRI image I can use to recreate the lighting at any level. I then unwrap the ball into a texture that can be placed on a skydome for accurate reflections and lighting using global illumination.
