If you do go used don't get an outdated surround proccessor. Make sure it does the latest surround formats and has room eq. The Denon you are looking at would definately fit the bill but with your budget I would go with a new 3808 and go used on the speakers.
As for the source, the Oppo's do a great job if you use the digital output and let the receiver do the digital to anolog conversion. As for bluray, the PS3 is the best deal out there performance and price wise at the moment.
