Please help, overclock settings for this hardware

Hardware:
2 x G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-2GBNQ =4GB total

Intel Core 2 Duo E6750 Conroe 2.66GHz LGA 775 65W Dual-Core Processor Model BX80557E6750

2 x SAPPHIRE 100259L Radeon HD 4870 512MB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card in Crossfire


Goal is to get maximum OC with this hardware. From what I've been reading 3.6Ghz is within reason. Now my question is what settings should I adjust to get maximum and boarderline safe overclocking. My knowledge on overclocking is Intermediate at best. I've had my PC set at 3.0 Ghz for a while now, but I want to see if I can push some more out of it.

This is what I know:
450 FSB with a 1.424 voltage will get me 3.6Ghz per Tomshardware testing.

Now my question is what other settings should I adjust in my bios. Memory overclocking is where my knowledge is very limited, like timing, voltage, and speeds. Also do I need to change any bridge speeds? What should I adjusting in addition to the FSB and Voltage for the CPU?

Any help would be greatly appreciated.

I plan on running Prime95 to test once I have everything adjusted that I need to.
