Ditch the DSP all together. dbx's new driverack is just another way to make money. The QSC boxes have built in EQ, limiters and crossovers. Thats all you need. And, the 01v96 has parametric EQ on the outputs and packs the ability to delay the outputs. Between the mixer and speakers, you can do just about everything that the driverack can do.
Get the matching QSC subs and you will be set. Dont waste your money on CV shit. It's DJ grade stuff and the QSC boxes will serve you a lot better. Or, check out the Yorkville LS800p. It's got a little more get up and go then the QSC sub. They are highly favored around here.
As others have said: ditch the sub mixer. Just get the ADA8000. That will give you 20 XLR inputs, and all the gates/comps/efx you will ever need. Plus it will clean up your setup a lot.
Personally, I would ditch the wireless vocal mics for hardwired mics. I just prefer working with wired mics. There are so many less issues to deal with. No batteries to change, no frequencies to deal with, and no drop outs. Just get some Shure SM58s and be done with it.
For drum mics: Get the Sennhieser e604's, and an Audix D6 for kick. Do you really even need over heads? You said you are playing rooms for ~200 people. I wouldnt bother micing overheads. Maybe hi hat, but not overheads. There will be enough bleed elsewhere.
For guitar mics, get the Sennhieser e906's. They sound great with very little EQ.
For snakes, save some money and go EWI. Check out
www.audiopile.net. Very good value snakes on there, and they will last.
Good luck...
