Overclocking's not for the faint of heart although there are some good guides out there. 3.3-3.6Ghz should be doable on the stock Intel cooler although if you want to hit 4GHz then you'll want a decent third party cooler. Megahalems are the best, in my opinion. I looked into loads but ended up settling on them and I've been running at 4GHz+ for months now on a pretty poor overclocker of a 920.
As far as the hackintosh part goes, head over to insanelymac and do a lot of reading. You'll really want to get to know the ins and outs of kexts, bootloaders and the like. While it's possible to do it as a complete novice using certain install builds, you're far more likely to end up dissatisfied if things get messed up after an OS update and you don't have a deep enough understanding to fix it yourself.
