take donald's advice jay. you don't need top of the line stuff yet, start with some decent markers and work your way up and develop a preference for different things. since you should be on paper, try getting some paint markers made by either sharpie or decocolor. and get some colored pencils and experiment with that stuff and expand accordingly. try out these sites:
bombingscience.com like arnor said,
artprimo.com,
33third.com,
and oinkartltd.com
stick with the basic generic stuff first.
thanks man. you should check out two writers; Daim & Peeta. they do crazy 3d style shit like you're drawing.
