Benny, I think that there is something out there for that specific reason. It is an adhesive pad that is placed where your palms rest. It is a slightly darker grey than the titanium and actually looks quite nice.
As far as the painting is concerned, I am pretty sure that doesn't void your warranty. Also, I can't say that I have seen a black powerbook, but I would love to. If you proceed with the mod be sure to take plenty of pics and document your work so that others can see.
