overclocking is a very very involved process. you'd be better off going to the overclocking forums. Before you do anything, do a google search for guides. You asked more than you realized here
as for what program you will be using... unless your motherboard makes an overclocking utility, you'll have to use the bios. Overclocking is a long process and no one can tell you the exact settings you'll need since every chip is just a little bit different.
