I have the temp senor in the pan of my 64 SS Impala just because it was the easiest place to put it. But GM also puts the temp probe in the pan also on the newer electric transmissions as in my 4L80E. I know because I have it hooked up and use it all the time in my 71 C-10.
My thinking is as long as I know the total degree of the fluid after it's been through the transmission and it's less than 200* as GM likes it to be I'm good.
If the temp starts climbing I know something is wrong.

As far as the aux cooler goes yes if you can get one big enough to handle it on it's own then go for it. I had limited space for mine so it is what it is and as far adding heat if everything is working then it shouldn't add muh of any heat.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
