I think you're selling yourself short with that Oinker. I was going ask if you had run the auto setup and noticed that it only has Audessey 2EQ!? This may not appeal to you at the time, but I'm sure part of the reason you're going with an AVR is to future-proof your setup as much as possible. IIRC 2EQ is below MultiEQ, MultiEQT, MultiEQXT32, and the new Audessey DSX. Even for $500, I think you should be able to do better with your hard-earned money.
If you like how it sounds though I think you have a good starting point.
