What your readings mean is some of the air used to make the pressure dissolved into the coolant. 2/3 LB really doesn't mean much. If you can pump the pressure up to 14-15 psi and hold it there for 15 min without seeing the car piss coolant all over then you can be confident in your work. I would recomend tightening the clamps on all the hoses you can reach after the car reaches operating temperature. Other than that it sounds like you're "good to go".
