If you are refering to the surfaces ie skin/materials they can be adjusted via the surface tab. If you are refering to the supplied shaders library both Daz originals and Iray then they can be found in your content library.

The layout can be a little different depending on your option set but there is a node based editor similar to Poser. Click on the windows tab to choose options you wish to see as tabs

Materials/textures that come with products both default and additional options appear usually in the same folder as the product in your Smart/Content Libraries along side their wardrobe/prop files. Addons for certain wardobe/props under their own pack name. Layout is a little different but it is similar to Poser in general concept.
