For number 1, disturb the surface with bump and you'll get disturbed reflections as you seem to want.  I'm sure there are other ways to do it but imo that's the most straightforward.

For number 2, I think Bagginsbill showed a long while back that most of those inputs in the PoserSurface root nodes do essentially the same thing, bypass the lighting model and just output diffuse color, so whatever goes in will come right back out with no regard to lighting except for specific nodes like Reflect that are designed to handle lighting themselves.
