Micah,
If you have a budget to purchase something like that $2500 EP800 I would serious consider purchasing these items.
Galaxy CM-140 or if budget allows a PAA3 and a great mike.
Behringer DSP1124P
M-audio Fast-track pro 4x of budget allows a MOTU Ultralite MK3
Download roomEQ or buy a trueRTA license.
Prince range to get the gear is from $200-1000 bucks and you should be able to test and calibrate with the best of them. If your ear needs training buy this book.
