I will defer to Richy & Edgieguy on the product/application specifics. But my thought is that if you clean the vehicle really well (get the dirt and grime off), then wax it (no polishing), that would get you started on a good footing.
Ideally, sure, you would throw in claying and polishing steps in between to achieve those diamond like sparkling results If you are interested in going whole hog, might be better off using a "test subject" (an old car, usually, or a painted panel) to get the hang of the process before using it on your "live" vehicle.
Or, look up well-reviewed detailers in your area to put your mind at ease. Maybe someone on here knows people in CT who you could go to or have come to you?
