Welcome to the forum mocatdaze. I cannot answer the questions as well as others here can. But I can say that since you have a brand new car you do should not need to use clay bar (unless it has been kept outdoors and the paint has collected contaminants). Also some people insist that you should only wax a new car a few momths after you bought it. This is because the paint is new and needs to breathe.
As a black car owner let me also say, be prepared to work hard to keep it clean. More importantly becareful how you wash your car, move the mitt in one direction only (I do it front to back), do not let any bird droppings bake under the sun otherwise you will definetely need a PC.
Good luck and enjoy your new car
