get a rudimentary book on lighting, one with setup diagrams, then do what
the pros do....copy something else they saw in a magazine!

borders or B&N will have a few guidebooks. they are all the same though. and
before considering a "kit", consider one light with a couple of light
modifiers. i know a few people that have lights collecting dust, because
they can't think of a scenario where they need three or four lights. and if
you do, then you will have done what i stated at the beginning.

actually, learing to artificially light will help you learn to light better
in natural light too.

That's a great book, for somebody who wants to know the underlying
principles and get a broad introduction to all the techniques available.
 It's not a cookbook for getting a few specific results -- which might
be a better way for some people to start out (depends on how you learn;
I'm better off with the decent theoretical book from the beginning).
