Sure it is exaggerated, as far as I know this was the first image that was done this way, so I see it as an experiment.
About the bump map: Yes, here's the point - it is useful because it adds roughness (pores and "goose skin") to the texture. To explain it the simple way: A bump map is a desaturated version of the skin - where black is the deepest point of the mat and white the highest. But if it would be easy like this I would not spend many hours when doing my bumpmaps. Regarding on what I said about black and white: If you just desaturate a texture the brows would appear sunken as well as pubic hair and spots, freckle and such. So a good bump contains parts that are inverted and some things like freckles will be covered with plain skin so that they do not appear sunken but flat as they are in reality.
In other words: You need a skin texture and a bump-texture, if both are from one set they match best (eyebrows and such).
Lights, well, they're hard to describe in words. How many? As few as possible, P6 doesn't need those masses of light anymore. The highest number of lights I ever used with it where 5 I think. Most of the time I get away with 1-3 (most 2 spots, one infinite). To get a shine on the skin one of them should highlight the surface or contour, depending on pose and camera angle. There is no easy solution for this, you'll need several tests. Use shadows below 1.0, Min Ray bias under 0.8 (0.6 is a good starting point) and shadow map-sizes, well, I recommend this thread

face_off posted a link to a tutorial there.
Maybe you will encounter much longer rendertimes with all those settings but well, good things take their time...
I'm not always right, but my mistakes are more interesting!
