Fuel pressure might be a bit obscure unless you are doing some manual tuning on your laptop with a good tuner program, even then tho it would be displayed on the tuner program. Oil temp is another good piece of info to have as well, it will really let you know when things are being pushed hard.
And, since you are a sling wing guy you may want to go ahead and put chip detectors on the engine and trans drain plugs and then get an N1 gauge for your turbo.....
Fuel pressure is important on my diesel so I know the lift pump is working and supplying the proper pressure to the injector pump.
Low lift pump pressure (or none) quickly kills an injector pump on a diesel,even if it is a draw through lift pump design.
Better to know when that 100 dollar lift pump needs replacement than to wait for a 2000 dollar injector pump to go south for want of that 100 dollar fix.
Transmission temperature speaks for itself, same as oil temperature.
IAT is important on a diesel as it has a direct effect on the EGT, but not as important as the EGT itself. On my 6.5, a rapid rise in temperature can be seen as boost builds. The GM-8 turbo starts to loose efficiency and get into the NE corner of the turbo map at around 15 psi. Rising IAT's can be monitored with a gauge as boost gets there and tells me to "back off".
Here's a quick photochop of what it's going to look like with gauges and the wallpaper on the touch screen:
And here's one with my Water Methanol Injection controller installed:
