I've ordered a pump/gauge that will let me quickly and easily (may be subjective) add or release pressure from the rear shock as needed. For my weight, riding solo I'll need it around 30 or 31 PSI, and if I add the wife I'll need to go right to the max of 72 PSI. Two questions:
1) Would I be better off actually changing the air pressure each time, leaving it at the higher pressure regardless of if it's just me or the both of us, or finding some middle ground and leaving it there?
2) Should I really go all the way up to the max of 72 PSI or keep it lower, around 70, to be on the safe side? The book seems to be pretty adamant about not going over 72.

Well, I have an XCT, not a Vision, and I don't really know squat about the Vision suspensions.
That said, the figures seem to be what the owner's manual say for the Cross bikes.
And THAT said, I don't go by them. I usually ride 30 - 35 PSI for me, and do most of my riding solo. And I'm 200+ pounds. If my wife gets on, and it's not a multi-day trip, I usually leave the shock at that. If we're going for a significant trip, however, I'll pump it up to around 40.
We've tried higher pressures, two-up, and 50, for example, is just too harsh, is our experience. I'm not saying that we never bottom out at, say, 40 PSI, but it's very rare. The tradeoff with higher pressures is just riding all the rest of the time with too much jarring.
Exec summary: IMHO if you leave the shock set at 72, either solo or two-up, I think you'll find it too harsh (unless you're doing a two-up track day). I think you should experiment with much lower pressures.
