Well.... I'm not going to give specific brands etc.... but here is the breakdown I would do.
1) AVR..... here you'd want to spend $300-$350 for a Yamaha/Sony/Onkyo etc that handles the new codecs.....
2) Front L/R/C You're going to want to spend about $1,200 of your budget here.... it's the most important.
3) Find a cheap pair of bookshelf or satellite speakers for $50 each for the surrounds....
4) I know I said I wouldn't give specific recommendations on brands, but with $300-$350 left in your budget, you can get a sub from Elemental Designs....
The FRONT L/R/C is the most important area of your HT.... I know many people think you should spend $700, or $800 on an AVR..... but I'm here to tell you, speakers will last YEARS.... AVRs drop in price and get phased out MUCH quicker...
My cheapie AVR handles my power hungry speakers, and costs about as much as ONE of my surrounds...... I see some people spend $150 on a front tower, but spend $800 on a Pioneer Elite receiver..... I don't get it, because the system is only as strong as its weakest link, and the front soundstage is THE most important area of a HT.
Sorry....went on a tangent or two
