Nobody can tell you what would be best, YOU have to listen and find speakers you like.
Well, since you're in Daly City, I'd take a trip over to Music Lover's in Berkeley and listen to their offerings. Then you will get a good idea of what that kind of money is going to buy you. I'd place focus on a single GOOD sub (SVS, HSU, etc...) and a solid front 3, and then add whatever surrounds the rest can buy. Music Lover's does carry Paradigm, so I'd probably listen to the Studio line.
