Monty,
Yes, you are using way too many mics. 2 great quality condensers should be maximun number of mics. Anyway, here is something to try.
When I first came on staff at my church a year ago they had 3 booms with one mic on each boom. I knew that was at least 1 mic too much. Well instead of fighting this politically and all that junk, I just scooted the 2 outside booms slightly closer to the center boom and I muted the center boom on my console. This way all 3 mics are still up there (at least visible) but only the outer 2 mics are actually on. Nobody is the wiser and I was able to put the console EQ practically flat instead of cutting out bass and mids. (which you can imagine cutting bass and mids not real good for the baritones)
By the way, 25 people I would think it would be better to make each row longer and only have 2 or 3 rows of people NOT 4.
Anyway, try and just mute some mics on the console and see if you can boost just a couple and EQ accordingly. This just may work out fine. The 3035 should be an adequate mic I've heard these before.
