Unless you have a significantly different cooling system than what came from the factory, the block should rid itself of any air bubbles rather quickly after you fill it up and run the engine. A couple things you can do to help the process is unscrew the coolant temp sensor from the coolant outlet on the side of the head while the engine is running (but still cool or lukewarm) and bypass the thermostat so that there is no restriction to the flow of coolant upon initial start-up.

I've mentioned the general method of bleeding a cars coolant system; if anyone has a more specific trick to bleed air bubbles from the coolant system on these cars please post it up! This is a good general topic to cover...

*edit- I'm sure you know already, but it's best to use distilled (not "mountain spring") water along with the coolant...I've been running tap water in my daily driver and consequently have already noticed calcium buildup inside hoses I replaced not more than a month ago...shame shame

Make sure your heater valve is open when you fill. Run the motor with the radiator cap off, squeeze the upper hose. You can also raise the front of the car up on a jack. Use 50/50 distilled water and blue BMW coolant (you won't get corrosion ever with this stuff).

I've never had an issue with air trapped in any of my cars.

I've cut one of those Prestone flushing tees into the left side heater hose and just crack the cap on it when i'm filling the radiator until you get just coolant and no air leaking out since I started doing this i've never had a air lock in the heater. The t only costs about a $1.50 and is well worth it and it lets you back flush the engine when its needed.

changing your coolant mix on the prescribed schedule (faithfully!) will keep corossion away, no matter what brand you use (so long as it meets specs). also make sure you WARM UP THE CAR until the heater blows HOT air, then rev it some, blowing out the air bubbles. top it off, cap it, and drive!! (no need for exotic fixes!! )
