OK andrew, heating is an adventure! First of all, I didn't read anywhere but is the heater vented? That is a must!
Secondly, you should be venting, fresh air intake into the greenhouse is a must. I know your cooler brings some in but convective cooling would be a good idea, even if humdity will drop.

That way the exhaust fan doesn't suck out the extra humidity. That can tend to be a problem if your sucking air through the pads with an exhaust fan. A friend of mine has that problem so she runs a fogger to try to increase humidity.
In Georgia you have trouble with humidity? I'm surprised you're worried about the little extra percentage that will be sucked out. Mike Catalani had a wetwall in his greenhouse run by his exhaust fan, thats how mine works too, dual stage stat 1st kicks on cooler, second kicks on fan, done deal. You wouldn't want to just push air through it and not exhaust it...wouldn't get a good air exchange plus it wouldn't cool that well.
Andrew, your cooler is fine for your greenhouse, a wet wall would be impractical for your ghouse. Not enough room.
As for the partitioning deal, I think it would be a good idea! Save your money! Save heat! The temperate plants should do just fine, perhaps increase shading in the winter so the photoperiod is a little more "natural" for them.
Up here i grow everything together all the time. The only difference I do for the Sarracenia is place them on the ground where it is colder. Water them 1 time a month approx....some even dry out...thats about it!
Any other questions?
