Nothing hard to do.
For a basic overclock, change your FSB from 266Mhz to 333Mhz, set your CPU voltage to 1.325V and make sure your RAM is at it's stock settings. To push it a little further, you will probably want to upgrade your CPU cooler. Not really hard to overclock. Just give it some extra voltage and turn up the FSB
I would agree that 3.2Ghz, 400Mhz * 8, with your RAM 1:1 with the FSB would be a great place to have it. You could probably hold this overclock stable very close to stock voltage.
