I am in a bit busy right now, so just a fast response to the displacement issue: It looks like your displacement map is not neutral on average, and therefore makes the mesh swell overall. The Poser displacement uses 0 (black) as the neutral value, and accept negative values for depressions. If you use a displacement map with gray as neutral, you have to set up math nodes to transform gray to 0 and darker tones to negative values: Just subtract 0.5 from the displacement map. How do you generate the map? If you use ZB2, you should be able to get the same look in poser as in ZB2. More comments to the shaders later.
