Looking for a good guide

This week I am building my first computer:http://pcpartpicker.com/p/wH1p. I want to learn how to overclock my 3570k to 4.2-4.4ghz on the asrock extreme4. I would also be interested in learning how to overclock the gpu. Does anyone have a good forum post/guide to go through? There is a lot of information on the topic but I'm not sure which ones are the most trusted. What other basic tips would you give to someone new to this hobby? Thanks in advance.

 

Regards.
