There's a lot to learn, Jim, but it's not really all that tough.
Pool care (water maintenance) comes down to 2 1/2 things:
1) Sanitation: That's chlorine to kill pathogens and break down bio matter
2) pH: How acidic or alkaline your water is.
2 1/2) Stabilizer to determine the proper level of chlorine.
Total alkalinity is mainly a buffer for pH, once you've eliminated obvious causes for its rise or fall. After that, if pH is rising too much, you generally lower TA. If pH trends down, you raise TA.
Calcium Hardness is useless in vinyl pools unless it's too high, then scaling can happen. In masonry pools (concrete, tile, etc) sufficient calcium in the water helps keep the calcium from leeching out of the walls.
For correct stabilizer levels, see the "Best Guess" table:

Not sure how you got a CYA # of "32". I presume you either got it from a pool store or guessed at it.
Normally, for a CYA of 30 to 50, we suggest a shocking level of 15ppm for your FC (free chlorine), and, generally, a maintenance level of 3-6ppm.
But you have an SWCG system and those usually require a CYA level of 60 to 80ppm. Correspondingly, with an SWCG, an FC level of at least 5% is recommended, which would be 3 to 4. But you CAN go higher if you need to. I generally do.
BTW, I use the BBB method and have an SWCG--an Autopilot. Remember: SWCG stands for salt water CHLORINE generation, and in your pool, chlorine is chlorine. All of us who have SWCGs occasionally supplement with other chlorine forms, but most usually bleach/liquid chlorine.
