Welcome to the forum.
Take a day and visit as many of the audio shops in your area as you can. Take along a couple of CD's that you're familiar with and audition as many speakers as you can. In addition to those in your price range, listen to some above that range just so you can get an idea of what's out there. All the while, you can be deciding whether or not you want floorstanders or bookshelves for your mains, etc. Also spend some time reading this and other audio fora to get an idea of which are generally regarded as decent speakers.
Among the brands I'd try to audition: B&W, JMLab, Klipsch, Monitor Audio, Paradigm, Polk and PSB. Another route to consider -- purchasing on line. It's a little bit of a hassle in that you'll have to actually purchase the speakers to audition them. Most all online companies have liberal return policies which require you to pay return shipping if you don't want them. For the hassle, you'll get an opportunity to actually audition the speakers in your own home. Another advantage, according to those who advocate online speakers is that, with no middleman retailer, you'll get more speaker for your money. Among the online brands to consider: Ascend, Aperion and Axiom.
Good luck!
