As long as it stays waterproof the internal heat has nowhere to go period [except through the case]. Perhaps a heat pipe to outside the case?
Your right. Air flow becomes essential and this would do the trick. This will necessitate a design change and more water proofing challenges. I suppose running it for a week in its present configuration in the current temps (mid 80s outside) would give me a more accurate feel for the temps and what might need to be changed going forward.
As long as you monitor the heat and have it turn the thing off when it gets TOO hot that should work. Maybe something that can log both the outside ambient temp and the internal temp too, that way you can see any correlation between the two.

Yes. For those new to Piz a look at devices available on http://adafruit.com (under the "shop" link at the top of page)and other such websites might surprise you. They have temp and humidity sensors that would "correlate" the two as suggested by you above.

Yes. Pi's chip is designed to run a lot hotter than a desktop as phone cases are well sealed. If you don't crunch on the PI at the same time you are using it as a camera you might not tax the chip so it overheats. Also the chip will slow down if it gets too hot and even turn off if it gets scorching.
As to sensing, I don't think you need an ambient sensor in the case, I think the chip temp sensor is what rules. You might consider though putting outside sensors on it and make it part weather station in addition to remote camera. Maybe a project webcam + full weather station. Up to you what you want to do.
The following link might add some other "thoughts" to using a Raspberry Pi as a camera. It shows how to adapt different lens mounts (C-mount for example) to your Pi: http://www.truetex.com/raspberrypi . Scroll down to see a telephoto mount OR how to turn your pi into a microscope.

Well I completed the build.
