Thanks Guys. I haven't played in a band situation with this rig yet. I think the volume is OK, although I'd love to get this thing out of my basement and try it in a different room/acoustics. The gain observation can be made with the master off ... it's more of a gain versus volume thing if you know what I mean.
Just do it the way the eden site recommends, and you'll be fine. Where your gain knob points is of no interest whatsoever, you know All it does is adjust the input to the proper level for the power amp to work with.
Now, if you couldn't get the gain light to blink with the gain dimed, that would be a reason to worry
