VSS can apply the shader using the textures you had before in your materials, but it has a few rules to do so:

-The Image_map nodes must be correctly named
-The Image_map nodes must be blank.

This means that, if you're placing actual images in your Template materials in the VSS prop, it'll use those exact images when it Synchronizes to your figure. That's why it's leaving your old image maps there, and using the same image you placed in the Template materials instead.

When you make your shader, in the Template (let's say Template Skin), create an Image_map node but don't point it to any image, leave it blank. Then go to you Python Scripts window, and in the VSS buttons go to Designer > Auto Rename Images. It'll rename according to what it's plugged to (so for this step you might want to link your Image_map nodes directly to Diffuse, Bump, Displacement, Specular etc in the poserSurface, and then fix the links after they're correctly named). Diffuse textures will be called Color Map, bump textures will be called Bump Map, and so on. With this correctly named and blank, rebuild your shader.

Reload whatever mat file you had for your character (so it has the correct textures placed again) and Synchronize. Worked? Save your VSS prop to library so you can use it again easily without having to set it up again.
