Need advice on OC settings for first timer w. i7 920 build

Just completed my first rig and everything is running great. Big accomplishment for me and I'm totally psyched.

I7 920 2.67 w/ D0 stepping (I made sure I got one from a batch that has been performing remarkably well, but who knows about my chip specifically)
Gigabyte x58 UD4P
Corsair 850w PSU
OCZ DDR3 PC3-12800 1600MHz 6GB Platinum XTC Triple Channel 7-7-7-24 timing (allegedly)
MSI ATI Radeon 4670 (soon to be replaced by 4890)
5 120mm fans going full speed in CM 690
coolermaster v8 cpu cooler.
Windows 7 RC 1700
running at 38C idle presently I believe.
I turn my computer off when I'm not using it.

Now, the next step is overclocking. I'd like to get the memory running as efficiently as possible and I'd like to do some mild overclocking that will be stable. I'm thinking 3.6 would be reasonable.

I don't know the first thing about how to check ram timing and testing it or how to do anything with the mobo or chip.

Obviously, I need some general advice about the order to do these things and maybe a reference or two.

If anyone has specific settings, and can explain where to go to enter them, that would be ideal.

Thanks all.
