Once you fill it with fluid after the install and the belt is on, get the front of the car up on jack stands and start the motor.
With the engine running, turn the steering wheel lock to lock about ten times.
Shut off the engine, and check the power steering fluid level again. If it's low, add fluid, start the motor again, and run it lock to lock again about ten times.
Check fluid once more, and the rest of the air will bleed out during normal driving.

I think if you change the pump alone, you won't have to bleed it. Any air in the vanes will work itself out. If there is a lot of air in the hoses, then a couple of stop to stop turns will take care of it. When you rebuild the whole system and it's full of air, it kind of helps if you do this on stands so you don't hve to work as hard turning the wheel, but even then, i think you can do it just driving the car.
Make sure you check the fluid level after a few minutes to make sure that you haven't foamed it up (air in fluid). if so, let it settle and top it off. No big deal.

It is always best to try and eliminate as much air as you can BEFORE starting your engine. When large air bubbles pass through a spinning power steering pump they get whipped to a froth with the oil. It then takes a couple days of erratic power assist before the air is eliminated.
