You pretty much have it down. Superchlorinating and shocking are the same. The point you are missing is that if you get your water balanced properly, get the CYA up around 80 ppm and run your FC at 5% of your CYA (for 80 ppm that would be 4 ppm FC) you will probably never need to shock the pool. Only shock if you have persistent (longer than 48 hours) combined chlorine over .5 ppm when testing with a GOOD test kit (such as the Taylor K-2006). Normally, there should be no need to shock and with the FC at 5% of the CYA you should not have algae outbreaks either (and for more algae protection and also to help stabilize pH even better the addition of 50 ppm borates to the water is highly recommended for salt pools.)

If you want to post a current set of test results I can suggest any changes you should make to the levels.
