My recommendation is to do some reading on how to overclock core 2 systems. Even with a relatively small overclock like .200ghz, there are a lot of things worth knowing.
There's a basic core 2 overclocking guide here in the forums as well as the almost endless info elsewhere.
That said you can mot likely just raise the FSB and leave most everything else on Auto to make it to 3.2ghz. You will want to set pcie to 100, and make sure your ram stays withing specs. Max cpu temperature for you chip is around 70c and 100c for the cores. Personally I would use Realtemp and keep the distance to Tjunction higher than 20c. Overclocking gets kind of addicting so you might as well read up on how to do it.
Your mobo should default to FSB of 333 and 9 multiplier to make 3.0ghz. So you will need a FSB of around 355 to get 3.2ghz. Make sure to set the ram to 1:1 or 710mhz and proper ram timings and voltage.
