Reply to Set up questions

So im looking at buying some cheap CD decks and a mixer so i can learn how to mix 'properly' (i.e. without a laptop). I've been mixing on a mixtrack pro for about a year now and still want the option of using traktor when i get my new set up. My question is what do i need on top of: cd decks/mixer/timecoded cd's/rca cables/powered speakers/laptop/external soundcard (could i use my mixtrack pro as the sound card?)

Thanks for any replies
