I think you're right, a trans temp gauge would be a good idea if you're towing. And a cooler as well. I suppose the temp sender could go inline on the cooler output line. Maybe someone else knows of a better place though.
The sender should be on the output line, as close to the transmission as possible. This will give you the best reading to tell the highest temp the fluid reaches, and is the fastest to react to temp spikes.
The pan is the second best place to mount the sensor. It will give you a good idea of the overall transmission temp, but won't react as fast as the output line and will allways read slightly lower.. temp spikes can be absorbed by the cooler and the rest of the fluid and never be shown.
The input line to the transmission should only be used to mount the sensor if you allready have a sensor in the pan or output line.
The only reason to use the input line is to tell how efective the trans cooler is, and this only works if you know how hot the fluid going into it is.

Headers are the only way to deal with those old exhaust manifolds. The 360 in my old F100 had to have headers. If you do any towing, you will probably blow out whats left of the gaskets and you won't be able to get the new gaskets to seal the leaks. Plus, FEs sound sweet with headers and dual glass packs . . .
