Good luck- I know you'll get it all nailed down.
I'm going to try to clarify what I said earlier about the graphic EQ settings.
If you look your graphic EQ curve and try to guess what the center line of that curve is, it's about 4dB (ticks) above zero. So if you pull every slider down 4 ticks, you'll accomplish the same effect as what you have but with less possibility for overload in the system, plus the ability to add more level in a given frequency should you choose to do so (not reccomended tho).

Hope that helps.
