Could you perhaps use a universal remote that always sends volume up/down to the amp and can send a power off to all devices with the power all button? I use a harmony 200 remote from walmart that I got for $20 and it does the trick. You may also want to look into the CEC stuff that Lars and pulse 8 are working on. The issue with the HD PVR transmitter is the firmware with the possible transmit signals looks like it only has support for cable boxes and satellite boxes. I'm not sure if it will be able to do much with your TV or amp. Also, the IR blaster only has a small beam so you probably wont be able to face it to see all of your equipment at once.
