Next would be to re do the gable ends with an attractive material. Back at the ceiling, I would install vent chutes from the wall to the ridge on the underside of the roof deck, then 6" of fiberglass insulation covered with more white pole barn steel, my personal ceiling of choice due to its speed of installation and low maintenance.
