Why not try out bagginsbill's VSS utility?

With VSS, you change one shader template (in a prop) and then click a button to apply it to all the relevant material zones in your figure (e.g. all skin materials).

Plus, the pre-loaded skin templates that it comes with are excellent, especially if you have Poser 6 or 7, since they have built-in gamma correction.
