I would also get a Wideband so you can know exactly what your AFR is then tune your jets properly rather than relying on their just their jet chart. The days of 'pill it til you kill it' are long gone.
Sounds like a lot of hassle to run nitrous. Do they make a retard box for our trucks? I checked into this a while back and found Mallory made a good one for Chevy LS1 engines that seemed flawless. And MSD had one for us but as I remember there was an issue with what spark plug wires could be used and I just gave up from there. Now come some more dumb questions as far as pulling timing is concerned. What are the timing degree differences between a 87 tune and 93 tune in numbers or do you know? Do you have to pull timing when you're running a stock tune or 87 tune? The retard box is supposed to automatically retard the timing a the time the shot or comes on when the nitrous is armed. On top of everything you mentioned it seems like that would save a lot of hassle for people who like to keep their existing tunes if it were possible.
