Half of that is lighting. There are at least two light sources based on the highlights of the tubing. The soft shadows makes me think there is probably some global illumination (GI) going on as well.
Focus on one material at a time.
It looks like they started with existing photos of textures, then gave them depth using bump maps. Search around for some tutorials on texturing different materials that might be similar, and then tweak them. And/or, find stock material that are close and try to modify it to match.
