for the light what you want is a few infinite lights set up around your scene and then use this for their material Set up this way, the light will light up your scene in the preview so you can work but will not render. You want to mix this with other lights that do render or use these when using a sky dome for final render lighting.

I have a set of these with my P11 light set http://www.sharecg.com/v/86639/browse/11/Poser/Studio-Portrait-Lights-for-Poser-11-Poser-11-Pro
