Point in the right direction

Hi Guys,
Im new to Tom's Hardware so firstly hello  

Im wanting to corectly overclock my rig but i dont have any idea what i should be setting things too, i dont want to damage anything.

What ive got
Motherboard - Asus P5NE-Sli
CPU - Intel Core 2 E6600
Ram - 8gb DDR2 OCZ ram (2gb chips) 5-5-5 @ 1.6v
Grafix Card - Gigabit Geforce 8600 GT
DVD writer - Asus DRW 1814BL
OS - Windows 7 pro 32 bit
Hard drives - both sata one Seagate 320g and a western digital 1tb

Ive flashed the bois to 1406 as per asus website but thats basically it

All this is running in a thermaltake Soprano case with a thermaltake 700w power supply

If i need to supply any extra info please let me know, otherwise i nudge in the right direction would be fantastic.

Also considering cooling the CPU with an Artic Freezer Pro (thoughts)

Many thanks
Andrew
