It depends entirely on the PSU, a GOOD 350 would work great. The MAXIMUM (non-sustainable) output of that Fortron unit is 440 watts, well above the 350 rating. A cheap noname PSU of the same capacity might be labeled a 440 watt unit - their idea of rating a unit is a lot different! Anyway, the Fortron unit or those two 400 watt units would work great. I've used Allied, and as I've said they dont leave as much room as Fortron, Antec, etc, but its a higher rated unit so they'd probably be pretty close. So I'd recommend the Fortron, but the other two would work fine, if you feel you want two fans in your PSU (sometimes it is necessary, other times its more for looks) you can grab the Allied unit.
As for HSFs, I can't stand noise so I typically avoid "high-end" models. My computer is too close to my bed, so I can't leave a noisemaker on at night. Actually, my current HSF was originally an all-copper vantec noisemaker model, but I removed the 60mm fan and installed an 80mm fan with an aluminum adapter (plastic being the alternative). It has a comparable CFM rating to the old fan, but is quiet. Anyway, some of the volcano series, like the 11+, look pretty decent. But very pricey. Most of the others suck (or don't suck? like cheap vacuums). If you're going to get something that expensive, might as well get an Aero 7+. The volcano 7 is OK for the price, so either get something inexpensive, or if you really plan on overclocking, get a volcano 11+ or Aero 7+. There are a few others that are good that are either quiet enough or can be tuned (as those two can) to be as noisy or quiet as needed.
