There are many different cases and screen covers out there, but the Incipio case + Zagg screen seems to provide the most protection. I use my Tab like that all the time, and for serious work (like cloud computing, I'm a writer) use a folding Bluetooth keyboard. Terrific combination, and I get my buck a word anywhere...
1. I attached a belt clip to the polycarbonate part of the Incipio case, and let it dangle. Super geeky.
2. After the Zagg screen has fully dried/cured, etc. wax it (really). Super slicky.
