In general I would say "less is more".

In daylight scenes, one light (the sun) and MegaPov radiosity. If you 
don't want to use radiosity try it with shadowless fill lights.

In Mike's example (used in portrait and single object photoraphy), when 
the object has no hair/fur, you can leave out the backlight quite often. 
The Fill light can be replace with a reflection screen, use a white box 
and (MegaPov)radiosity.

Lots of information on this subject can be found in photography books and 
sites. But keep in mind that they mostly use a diffuse light source, 
something that is not available in povray (altough it can be simulated 
with "overly bright radiosity objects"). So contrast is a bit higher.
