Thanks for the reply. So I figured the vacuum dashpods were bad and were causing the issue I was having. I spent about 6 hours removing the dash, replacing the pods, and reassembling everything (although there are 2 screws left over that I couldn't figure out where they went). That fixed my front vent issue (knew it would) however the outer vents still stay warmish. I verified that the monovalve is getting 13.3v on the cold setting and 1-2v on the hot setting, however it may be weeping hot coolant into the heater core. I think that'll be my next replacement part.

I still have no good info on my #1 issue.
