I'll let others with far more knowledge respond but I'm curious if you've bought the speakers yet. Since you're starting from scratch, maybe it would make more sense to think holistically about your system rather than start with a pair of speakers and work your way "backward" to the components? Does your store specialize in AV/home theater? They should be able to put together a sweet system. I would imagine that if you look at your total budget, that will help give you a sense of how to prioritize.
Good luck!!
