With the extra channels of surround systems, processor loops are basically a thing of the past, making this sort of thing a bit tricky. I'm not familar enough with the Behringers to offer any specific suggestions, but there are a lot resources online - which you've probably already looked at...
2. Wouldn't it be much better to have a digital pre-out/amp-in setup? If I could but a 7.1 toslink equalizer, and the 990 had such an connection path, that would be great. I don't think equalization of the surrounds is critical, so 4 channels would be enough. However, I would need electronics that could separate the appropriate digital channels, feed them as digital inputs to the equalizers and then recombine them to send them back to the 990 to apply volume control and send the analog to the amp.
The idea has some merit, but the logistics could be a bit tricky. You'd want to put this processing downstream of the DSP and upstream of the DACs. What digital format to you use for the output? The only way I know of to pass eight channels of PCM (the most logical choice downstream of the DD/DTS/PLIIx/etc DSP) is HDMI, although FireWire could probably pull it off as well - coaxial and optical digital output probably don't have the bandwidth.
