Since you haven't said whay you own already (I assume that you at least own a CD player), I would say get some decent speakers and amp (if you don't already). That'll let you learn more and play music with more volume, and it will last you for ages you could just use in in your lounge room even if you didn't want it. More DJ-style equipment I can't really recommend for you, but I would say to try out stuff that friends/family own or at a hotel or club somewhere (maybe even get a job there). Then you will get an idea of what kinf of stuff stuff you can always expect to have as standard and what extra features you like.
