Blacksmith,
I bought a book that really helped me out.

Basically you use 3 shades for all your painting. It is actually a really nice way to paint and makes your miniatures look really good, even if your not a great painter.
I find that I excel using certain colors and suck with other ones.
Foundry sells their paints based on the Foundry System. A shade, a base and a highlight.
Some of the Foundry bases and highlights seem too off color for my liking.
The foundry paint sets that I really love though are
FLESH 5
FOREST GREEN 26
ARCTIC GREY 33
While painting up some rats I found that using the Foundry Flesh 5 Shade mixed with black is a great shade mixture for their flesh areas.
I love the Forest Green and Arctic Grey sets.
Acharnement
My thinking for basing the figures was to have Heros and such stand taller than the normal trooper types. The Heros bases are made up of a 25mm base with a 20mm base on top of it. I have yet to devise a really cool basing system for my figures.
I have a bunch of frogs on order that I plan on doing some sort of swampy base.
