Check out #default. You can use it to set default ambient to 0, and then 
any object you WANT to have ambient can have the value specified in its 
finish.

Only one way to find out... ;)

It may. With too low a count, the parts of the scene that are supposed 
to be illuminated by that "light" may not be able to find it, resulting 
in artifacts and poor lighting.

Generally, the smaller your "light" source appears in the scene, the 
higher the count will need to be to get accurate radiosity values. This 
is why outdoor scenes can usually get away with a low count.. the sky is 
a huge glowing dome.
