Anything I should watch out for? Help needed.

[sxcboi500]

I'm building my first ever pc and the components so far are

Antec NSK 2480 Desktop Case - Black/Silver (380W Earth Watts PSU) £89.99
Intel Pentium Dual-Core E5300 "LGA775 Core 2" 2.60GHz (800FSB) - Retail £52.99
OCZ Gold Edition 4GB (2x2GB) PC2-6400C5 Dual Channel Series (OCZ2G8004GK) £41.39
MSI M3-F Intel G31 (Socket 775) PCI-Express DDR2 Motherboard £38.99
Seagate Barracuda 7200.12 500GB SATA-II 16MB Cache - OEM (ST3500418AS) £36.98

I've read all the newbies guides to overclocking but having never done it before I still have a few questions I'm afraid.
I'm looking to overclock my CPU and RAM. I'm using the stock CPU fan and was wandering if there was anything I should look out for as I obviously do not want to damage my equiptment. I've been reliably informed that the E5300 is ideal for overclocking because of its clock ratio?

Temperatures are what you need to look out for, and you wont be able to overclock it to its full potential with the stock cpu cooler, potentially to 3ghz, maybe 3.2 with it, past that i think would be too hot.
