50 would be good
Yes, way too high. 50-60 pounds is the best and a lot less strain on your fixtures.

Do you have any idea as to when or what gets you up to 140ish psi?
Yes 80 psi static pressure is typically the maximum allowed by plumbing codes. Anything below that should be okay provided you don't have any water hammering and/or too high a velocity in any of your piping.
I consider too high of a velocity when the flow gets a bit noisy or around 8 to 10 fps, or above. Examples: Above 6 gpm for 1/2" pipe, 12 to 15 gpm for a 3/4" pipe.
"The fluid flow velocities in water systems should not exceed certain limits to avoid noise and damaging wear and tear of pipes and fittings. The table below can be used as a guide to maximum velocities:
