The idle mixture screws are also nearly all the way out, maybe one turn in on each cylinder.

That's the normal position of the air correction screws. They're used to balance the airflow into each cylinder at idle since it isn't possible to have all three throttle plates in perfect unison (at least for idle purposes).
As for the idle mixture screws, they have more travel and adjustment range than one turn out from seated, which, btw, seems about right.
