While that PSU may be a good one you just might want to consider one that is slightly more powerful.
Not sure what it is rated on the 12V rails but a Corsair 520W can deliver 40A on the 12V which would be plenty for your system. Unless you already have the psu i would advise at something like the Corsair or something similiar from Seasonic.
As for a Cooler it really depends on how good of a cooler you want. The best air cooler is the Thermalright Ultra 120 Extreme. You also need to buy a fan to go with it, a Scythe S-Flex would be a good one.
For a cpu cooler thats a little cheaper but still offers good performance would be a Scythe Katana.
