Thanks guys .
Well, for the lighting, I kinda "cheated". I rendered a Color Pass, an Ambient Occlusion Pass, and a Specular Pass. Then I brought it into Photoshop and tweaked the layers to get this look (including changing the color of my white AO pass to a green-ish color).
I assume there might be a way to do this within A:M, but haven't got around to checking that yet.
