Regarding power and air delivery.
The importance of this cannot be overstated enough. Few things suck more than running out of panel, tripping over air hoses, etc. It just eats the clock and drags things out. Build your shop with plenty of power in reserve. I have an 800 amp main. In 3 years I've filled two breaker panels. (MO POWAH!)
Air:
I ran copper lines. PVC can work too, but I know that copper is drama free. I've seen PVC get brittle and fail over time. Especially in places where stuff is being plugged in/removed frequently. I ran my lines on a 1" per 10' angle so that any moisture runs away from the source. I placed drains below each coupler and the couplers are pointing up instead of down. Combined with a line conditioner (dryer) it's made for a pretty robust/trouble free setup. The caveat here is I discovered (later) that cheapo air hoses don't last. The gravity effect on them pointing up and then turning down leads to premature failure around the swaged end where the male hose end attaches.
If your going all out, consider radiant floor heat if your in a climate that needs that sort of thing. Warm feet in the dead of winter makes for a comfortable setting. Few things suck more than walking into an ice box Monday morning. You can blow all the hot air you want, if the floor is cold, your going to be miserable. Consider where you'll be in 15-20 years.
We all realize at some point that we have an expiration date. Plan ahead...
The floor should be smooth, level, and capable of supporting the mass of equipment. If your putting up a building, stress the importance of a proper floor. Cannot be overstated enough.
Consider LED lighting. 50% off your power bill compared to the alternatives and everything is visible spectrum light. No more piss yellow tints and headaches from UV emissions.
Good luck and hope this helps.
