Thanks to everybody for the detailed replies!
I'm gonna follow what seems to be the universal advice and check torques (thanks zebrafive), grease everything, change the crank case oil + filter, the hydraulic fluid + filter, and the coolant, and check all other fluids/adjustments (front gear box oil, brakes & clutch adjustment, etc.). I'll forget about injectors until there's a case for looking at them.
For oil I'll do a quality 15W40, since in NH we are typically in those temperature ranges. I'll match the filter from Napa or TSC. I'm not the first person on TBN to wonder about this for my specific tractor [Had a link but can't use links yet since I'm new]!
For hydraulic fluid, the manual calls for JDM J20A or B, depending on weather. That seems to be a retired spec, but I did find Hy-Gard at the john deere website which says it meets service rating (whatever that means) for J21A: Is that what I should use? I found it at greenpartstore in 5-gallon tubs.
I did find some stuff at wally-world that says it meets the JD 20A/B/C AND HyGard J14B/C specs, but I hesitate to buy my tractor hydraulic fluid from walmart...
For coolant, I'm going to go with the JD stuff again - Cool-gard II Concentrate from greenpartstore, mixing 50/50 with distilled water. The 950 manual says to flush with clean water (fill, run to reach temp, drain before particles have time to settle) and then use a 'cooling system cleaner'. I'm not finding any 'John Deere Cooling System Cleaner' anywhere. Should I bother with this step or just flush, rinse, and refill? I see some people mention using distilled vinegar?
For technical manuals, I discovered John Deere still has them all available at the john deere techpubs website (though at $150 per printed technical manual they are quite proud of them!). I have to call them to find out what the 'cd' entails (I remember these - thin, round, shiny?). I'm hoping it means I can buy one cd and then print myself a shop copy and reprint it when it gets too greased to read...
