Re: Plan of attack...
I agree with vance, other than the into method. Go ahead and remove the necessary frames to fit the package into the middles of the box, remove the queen cage and attach it to one of the fames near the center, go back in a 3 - 4 days to see if the queen has been released (look for her now on the frames to be sure she is there, easier than later), or release her, pull the package box and add the remaining frames to the hive, shake out the bees lingering in the package, then leave them alone or a good week or more.
Give them something to feed on, depending on your method, reduce the entrance to the minimum.
They are not going to drift because they are tuned in to the queen, so don't worry about placement or proximity.
Then cross your fingers for a good flow
