Noise cancellation never works on scales larger than the sound's wavelength, so it's only useful for headphones. Modifying the hall physically is the only real solution to this problem. Short of that, the first thing to try is indeed to bring the sound as directly to the audience as possible, by using a suitable PA arrangement. Big, single speakers located ...

I know that sometimes for concerts there will be "shells" around the ensemble, curving down and around the group. This will help reduce any noise escaping backwards. Not knowing the venue, this may not be part of the problem. It also depends on whether or not the ensemble is acoustic or electric. With electric you could point the speakers in different ...

Generally, yes - you would play it through headphones and set it up so it sounds as good as you can get, then back the reverb right off for playing it in a large room, if that room has a fair amount of echo anyway. If the room isn't too large, is full of people or has sound deadening surfaces (wall hangings, carpets, etc) then don't worry about it too much, ...

If you can't treat the room, you can try optimizing using the sound system and the band. Control sound radiation so it beams as much as possible towards the audience and absorptive surfaces and away from any reflective surfaces. Monitor wedges are the worst. They beam up and back directly at backwall and ceiling. Wedges have their place on large stages but ...

Another thing you can use is a high quality digital delay for the high frequencies through the stage mains since they travel faster then the bass frequencies. Things will sound less muddled. You can also use a 3rd and 4th speaker in the back of the room with the live mix delayed on the stage mains and the rear or mid-room speakers non-delayed. Van Halen ...

You don't have to modify the room to add physical damping to it. Velvet drapes absorb a lot of sound, even when they don't actually cover any surface, and would be very sympathetic to the decor. A few loose rugs covering unused floor areas, where the audience isn't directly looking at them, would also help a lot. The drapes and rugs could be put in place ...
