PSU, a quality 850W especially if you intend to overclock.
Cooling, depends on how much you have to sink into it. Most ideal would be a custom water-loop, but strapping an NH-D14 to the 3930k and using the stock cooling on the 690 would serve you fine.
That's a great cpu cooler I hadn't seen. I was tempted to purchase a ZALMAN CNPS 9900 MAX 135mm however not sure if it be better to purchase th NH-D14
