Oil Pressure

My ST is the first car I have had an oil pressure gauge. I have no real idea what it should be reading. These are my finding please tell me if they are normal.

Cold Start:
3/4 or above on the gage until warm

Warm Start:
Goes to 50% then comes down

Idle:
in the lower 1/4 area. Seems low to me

Driving:
around 50%

When the car had low milage the gage never went down to the lower 1/4 area. Now I have 2200 miles on the car it lives down there at idle. I'm guessing this is normal.

Questions:
Does the wear level of the oil change the oil pressure?
How much variation should I expect based on outside temp?
Does the now lower oil pressure at idle suggest the engine is now broken in?
