Trans takes 20-30 min to warm up, you are heating up almost 5 gal of ATF, or in my case over 5 gal. Anything over 200 degrees means you need more cooling. I use 215 to 220 as my pull over temp unless I am getting ready to crest the top of a hill. Cure for this is the True Cool Max ( Ford V10 Cooler) or the 6.0 cooler.
EGT's, most use 1250 as redline, but again if you are cresting the top of a grade I would stay in it. It takes over 2 min to heat soak a piston, so brief runs exceeding 1400 degrees is survivable, contrary to internet myth where the engine explodes at 1251 degrees. I have never had mine reach 1250, IIRC 1200 was the highest I hit towing heavy up a very long steep grade. Best cure for high EGT's is more air flow in and out, followed by water meth injection.
Boost should be one of your gauges, I would use boost before FP but if you can have both even better. Stock 15-17 psi is about all you will see. A tuned truck can see triple that, just remember anything over 25psi is shortening the life of the stock turbo.
FP will vary, but 60-70 psi is normal.
