my cousin went off the island for a week and left is router along with his laptop and me ever having my own pc can i do anything with my xbox thru these stuff ?

i live in the bahamas and came across only 1 store modding xbox for $99.00 dollars.i was surpose 2 find out the mod-chips name to see what all it can do by reading across the internet,anyway i have 007 the right name used for the exploit trick but no memory card.
do i need a memory card?
if so will the exploit thing work as if my xbox had a mod-chip and is it easy do do?

i like xbox and i have alot of paid for games,but its costing so much to have fun these days so sorry for all this writing but can anyone please help me out on my questions.
