Well, I tried everything suggested, alone and combined.  I still prefer the Poser 7 style render. 

I suspect there's still a lot of work to be done on hair shaders for new version of Poser.

(Image is EZskin Jessi with the Envirosphere and one infinite light set at 50%.  I usually prefer lower light than that; the skin already looks blown out to me.  Hair still doesn't look as nice as the P7 render.  IMO, of course.  YMMV.)
