You can setup a really nice 5.1 system without having to run cables to the rear speakers from your receiver. Check out THIS LINK.
If you want to get a great set of speakers see JBL. You could get 5 matching 580 towers for around $1500 and the matching 550P sub for $189.
As for a receiver I like the new Onkyo’s with Dirac room correction and my second choice would be a Marantz at a discount at accessories4less.com. Anthem is very good but might be above your budget.
As for a source Sony makes great blueray players.
