Intro system budget problem

Im new, and I mean the blissfully ignorant to anything Hifi new (dont take that the wrong way, I know its a fever :P). Well I just took my first step into the realm and purchased a pair of Ohm Acoustics Microwalsh Tall SE's. The problem? I need everything else. I have a $2500 budget now at $1000 dollars for everything else (will have future upgrade investments). In the 3-4 weeks it will take the Ohm's to ship out here, I would like to have something ready to use and (not)abuse them. I was informed by numerous friends that speakers should be the single largest investment so I threw a good amount of my budget at the Ohms.

Again I dont know much about audio, the setup, or specifications and I need everything, speaker wire, receiver(integrated?) and whatever else. What I know is my out of the box cheap walmart Sony receiver 5.1 HT setup in a small 12'x16' room. I stream music to the receiver via media server support from my computer. I have iPod but no connection to receiver.

I have done a lot of reading on this forum prior to me making my account today and I appear to have a very strict budget (for the hobby), and would just like to be at least pointed in the right direction before I blindly go about building my system all wrong in specifications.

Thank you for your insights!
