As far as refilling the coolant with as little air as possible here is what I did.
1. Since the thermostat and housing is off I started to fill from there till it was topped off
2. I attached the radiator hose to the housing and left it elevated
3. I slowly filled reservoir up till it ran out of the top of the radiator
4. filled the elevated end of the radiator hose and then pinched it off a few inches from
the end and attached it to the radiator
5. slowly squeezed the upper hose and continually filled the reservoir
6. started vehicle and just let it idle and added coolant as needed
This whole process took less than 10 minutes and worked out well
