I am looking for a new receiver to replace my HK AVR 40. (yes i know its old

)
I just bought the EMP e5ti towers and plan to get a sub from either outlaw, HSU or EMP real soon. Then keep adding from there.
I was looking at the Pioneer 1019 and saw it had some good reviews. CNET gave it top rating over its similar priced Denon and Onkyo counterparts.
I was reading around here and saw another post about the pioneer being weak on the AMP side especially with speakers with a sensitivity like the EMP.
I would like a receiver I can keep for a few years. Here is what I am looking for:
-500 bucks or below
-7.1 would be preferred but 5.1 is ok (prevent the upgrade bugs)
-most up to date codecs/decoders etc
-decent power maybe even the option for a amp later?
-doesnt get super hot or need to be seperated from other devices
-A usb port would be nice but optional that way I can plug in my Zune mp3.
Last question. Do i really need all the upscaling/1080 video functions? If I have a upscaling dvd or blue ray player? or PS3? Im not understanding the whole purpose of the video decoders in the receiver.
None of my past receivers had video codecs. I have owned pioneer, onkyo, HTIB and was given the AVR 40 recently when I decided the HTIB was junk.
