Okay most of your questions have been answered... but I have a little more to add. Once you have your shader set up, use the Blinn node and plug it into either the Alt Specular... or if you have Poser 9 or Poser Pro 2012 (which from your original post it doesn't seem like you do) then you can plug it into the blender node along with the scatter node.

Now with it's default settings it will look decent, but the trick is to use a specular map (pretty much take the original diffuse map into Photoshop/Gimp, desaturate it, then use Darkness and Contrast to darken the image and bring out some detail, you want the grey parts to not shine as much as the white parts), then plug that into a blender node with a value of 0.5 with a noise node. My suggestion would be to make the x,y,z scale about 0.100... and put the Min: 0.400 Max: 0.400-0.600... just expirament, you want it to basically resemble glitter... this will create the "sweaty" look.

Also the lights, make sure that the lights have atleast a medium light color on "Specular Color" setting in the material room... and if needed you can add an extra light and set the "Diffuse Color" to completely black, and set the "Specular Color" to a desaturated ligth blue... this will create a "Specular Only" light. It will make the shine appear amplified, so if the girl is "sweating" she will be more shiny with higher specular settings... Also put the shadows as "Raytracing" and also avoid using shadows on more than 2 lights.
