I really, really like the free lights at RDNA. In a lot of ways they're like poses: even if there isn't one you like perfectly, they give you a starting point. At the moment I've got my Poser set up to start with one of their SoftLights (Flesh) that's been moved about slightly and totally desaturated. Gives a good bit of global illumination to work with while the scene's being built. :)
