I would say get at least 2 of each of the polishing pads-medium cut(2) and fine cut(2). You may want to invest in a smaller disc and pad set too for the smaller areas.
Most of the higher quality polishes, wax/glazes etc will be just fine for your car. The biggest thing is the prep work. Once that is done, then the final product will be outstanding!
Get plenty of microfiber towels. Maybe 4 for drying, 2 or 3 for the door jambs and a 4 for each stage of removing polishes etc. You don't ever want to re-use a towel or pad if it has dropped on the ground.
One thing-Clay bar. This is probably one of the biggest factors in starting your prep work. This is especially if your car sits outside a lot.
