In the screencap below, I outlined some changes that should be performed on the skin shader alone.  It should improve its appearance when rendered.

The character skin shader was designed with many flaws that in actuality were meant to work with the Poser versions earlier than Poser 2010.  On the PoserSurface node, each plugin channel is a multiplier, they influence the intensity of calculated maps attached to each connector site.  Notice in the image, that there are active Diffuse, Specular, Alternate_Diffuse, and Alternate_Specular channels; this means that the shader is doubling those maps, making them emit an ambient 'glow'.  To correct this, the Diffuse_value and Specular_Value channels should be set to 0 and allow the Alternate_Diffuse and Alternate_Specular to perform the calculations for the skin texture.  This will also give a more natural skin tone from the texture maps by getting rid of the color chips that are imparting unrealistic tints.

Set the Translucence_Value to 0, that channel is unnecessary and can cause self-glowing.  There are better ways to give the skin Subsurface Scatter through the SSS nodes introduced in Poser 2010.

Always uncheck the Reflection_Lite_Mult.  When used, it deactivates the Reflection_Color and Reflection_Value channels; this is a holdover from earlier Poser Versions and is unnecessary.

As for the pants, it's a simple shader arrangement and doesn't appear to be a problem.  I would disconnect the map at the Specular_Color channel.  I would also reduce the Diffuse_Value to an approximate value of 0.85; nothing in nature is 100% diffuse.
