G8rDuc, I can't tell the size of the metal studs but if they are 2-inches you might consider rigid foam panels. Home Depot sells 2-inch thick 4' x 8' panels that would give you R7.7 in the walls and R15.4 doubled up across the ceiling. If the studs are less than 2-inches you could use metal furring to get that thickness.
Vents at the top of the gable ends would also help. Make one of them solar powered and you can dramatically reduce the temperature at the peak. When that space is 140-degrees F or hotter, it will radiate heat into the space below like crazy. Once it's insulated and vented, a 110v 12,500 btu wall shaker would cool your garage just fine.
