Might look into mid/high diffusers for taming the mid/highs but cheapest solution is to turn down along with speaker and mic placement can do wonders for feedback elimination and doesn't cost any thing.
Also might use a 31 band EQ on the channel strip insert with a Y insert cable to notch out the offending FB frequencies if your using the main outs on your mixer for the speakers.

+1 on the 31-band Graphic EQ. It's an absolute "must" if you're trying to eke out the most volume possible, in a small space. It really is a combination of many things, such as the type of mics used, how they're placed,,, how the speakers are placed, how room reflections interact with your mic and speaker positions, and of course, overall volume.
We're practicing with a partially mic'ed drum-kit (snare/kick,rack-toms) so we get quite loud, but since I started using the dbx 1231, we've not had a trace of feedback. Previous to that, we had an annoying "intermittent" squeek at roughly 4KHz. It would only last for a tiny fraction of a second, so, it was hard to find at first. Turns out it was one of the vocalists' cheek, reflecting hi-frequency sound. He'd sometimes turn his face sideways to look at a musician beside him, and as he did so, he'd lean close to the mic (SM-58). There were other solutions available (swept mid cut on his vocal channel, and/or super-cardioid mic), but the 1231 was quick and easy..
