Opera: 1) I am using the 12/29/04 release of the shader. Last I heard, the shader had been fully updated from the hyperreal products and was still in testing. 2) The default lights suck, but it gives you the idea of an out of the box render just so you can compare how the shader is using the lighting. 3) There were no bump maps used in any of the posts except for the Adam2 with displacement. When you don't have a bump map, the shader gives you the option of adding noise to the bump node. I typically avoid doing this as I don't like the effects of either the shader's noise or displacement.
