Your numbers are fine where they are now since they yield a CSI of -0.26.
The decision to add calcium is going to based on the CH of your fill water, the rate of evaporation you expect to experience, and the average annual rainfall. I my area, with so little rain, we constantly fight rising calcium levels so adding calcium would only make the problem worse and require a water replacement sooner than if no calcium was added.
Once you add salt to the pool, your CSI will drop further to -0.49 (assuming 3200 ppm and your current numbers). It would be best for you to target a pH of 7.6-7.8 and maintain the TA around 60-70.
Use Pool Math to calculate The CSI for you. Shoot for +0.1 to -0.2
