Elkcrazy8,

You have got it right. Some of the rules are broad based covering all classes such as the 5gr/lb vs 280 fps rule. Other rules are class specific such as sights or stabilizer legth. You as a shooter must be aware of not only the rules specific to your class but also those concerning all levels of competition. If you or anyone else have any other specific questions, just continue asking. There are plenty of people around to help keep you on track.
