would it be necessary for me to buy an ASIC device in order to use it... These things are kinda costly for me.. Also could you tell me about some cheap ASIC devices... please help i really wanna be a part of this thing...
Yes, you need ASICs to mine. Forget anything else.
Unfortunately mining on cheap ASICs (USB sticks) is also pointless at this time. You need the bigger ASICs with low cost per GH/s and low electricity usage. You'll also need cheap electricity. If electricity is expensive where you live, then things will be difficult.
