Need Help with Overclocking FX 6300 Processor

Here is my CURRENT PC's Configuration:

Processor: AMD FX 6300 with stock cooler
Motherboard: Asus M5A99FX Pro R2.0
Video Card: MSI Radeon R9 270X OC Edition
Power Supply: 550 W

I am new to overclocking and hence I've been looking into youtube for tutorials. I couldn't get to conclusion that which one is safe to use. On the other hand, I will be receiving my aftermarket cooler within 2-3 days. Before it's arrival, Can anyone suggest me the parameters to use in the BIOS which would be really helpful for me?

Edit: Also, what are the programs that I need to download and install before starting the overclock?
