Just how much vacuum do you have to have on the pump meter to adjust this properly ? Thanks

at least as much as you have at fast idle.  I always check at 20 inches of vacuum.  i never tried but I think it pulls in completely with much less than that.

Can someone run that by me again on the procedure for setting the choke after the vacuum is applied ? Thanks

FOUR inches of vacuum has completely seated this Q-jet choke pulloff.
