I would not consider and amd for your first build you will be more then happy with 3.0. You setup looks fine. Everything is perfect I also just got that case and you dont need anything else with it. No special tools just a screwdriver and some zip ties and cutters for a little cable managment. The 380 watts psu is more then suffiicent. You can work with your bare hands fine, make sure that the computer is never plugged in and the psu is switched off.
Also why the nic card? I am pretty sure that the mobo comes with one. And if your going to get a soundcard I would get something like audigy 2. Otherwise your setup is perfect.
