what is the PROPER burping method when re-filling antifreeze/coolant into a 2.2L '99Sub/leg?

Not sure about the 2.2 but I did it on my 2.5 SOHC recently when I had to replace the radiator. Elevate the front end, e.g. on ramps. Take radiator cap off. Disconnect upper radiator hose, at the radiator. Pour coolant into the overflow tank to the 'full' mark.' Pour coolant into the block through the upper radiator hose, slowly, allowing it to 'burp' itself, until it (and the radiator) simply won't take any more. Connect the hose but leave cap off, start the car, run a few seconds, and in all likelihood you will be able to add more coolant to the radiator. Do this a few times, reinstall the radiator cap, and drive the car for 10 minutes or so. Allow to cool; remove cap; check level; repeat if necessary. This worked for me.

Yep - just about what he said. That typically works for me.

 

I will say that about 80% of the time, if you remove an old thermostat it won't work when you put it back in.
