Changing the IAT resistance changes the actual intake air temperature that the PCM sees. As a rule of thumb:
Colder = More Fuel and Slightly advanced timing
Warmer = Less Fuel and Slightly retarded timing
Adding slightly more fuel and an a little bit more advanced timing adds a few HP in the mid to top-end.
Yes, you can also do this on your 4.7L.

I would prefer more timing and less fuel at
cruise, for better mpg. And more timing, more fuel
at wot. Can this be done? Or are the two inseperable?

It's related to temperature...not just throttle position.
