Of course I favour advanced training and competent aerobatic training, but more simply, the stall/spin/spiral to final can be prevented by assuring that you don't allow the conditions which enable it to begin. Understanding what to to start, will prevent your having to recover from it.
Stretching a glide is a poor idea, particularly when there are turns yet to make. Thus, I like higher, more steep approaches where the traffic allows it. With a more steep approach there is less incentive to slow the plane too much.
Use caution when gusty winds may cause the need for a rapid pitch correction, particularly when that wind is not aligned with the runway heading.
Use landing flaps, but extend them when a stabilized approach has you in a place where you can safely continue the landing with that flap setting.
