1: I hosted on and old 3GHz P4, and CPU usage rarely exceeded 25%. RAM usage was generally below 512MB.
2: It's entirely feasible to host NWN on a plan like that--in fact, I did (and do) on a similar Charter line. You probably won't see significant lag issues unless something else is hogging bandwidth, or you have many players in a single area. You could definitely feel it on my setup when 20+ players gathered in one area, but that's fairly rare.
3: If starting from scratch today I'd definitely give some flavor of linux a try. It's lighter on requirements, and more NWNX plugins are kept up to date for it than Windows.
