I am new to overclocking so i have lot's of questions

I have a amd athlon xp 2000+ with a ecs k7vta3 v5.0 motherboard.
Is it possible to overclock the processor? I have read that most of the xp processors are locked and can be unlocked by connecting some bridges. Is this true? And how do i know is lokced and what bridges do i connect to unlock it, if locked.
Also i would like to know if it is possible to run this amd at 2.0 ghz it is running 1.67 standard by the way. And what cooling is best for this. I have read on the internet that somebody is running it at 1883 with standard cooling.
I have also rad it is recomended to overclock through highly adjustable bus speed settings. does anybody know if my MoBo has them?
Hope somebody canhelp me with this , and hope i can run it a litlle bit faster
