Thanks!
For that pool the TA level is not all that critical (unless your fill water is very high in calcium). Anything from 70 to 120 should be fine, though it should probably be on the higher end of that range if you are using trichlor or dichlor.
The CYA level is a bit high. I assume STA means stabilizer which is CYA. If you are using trichlor or dichlor you are about to have serious problems (CYA will keep going up and that means trouble). Using bleach it is manageable at 90, but lower would be better. With a SWG I suggest CYA of 60-80, without a SWG 30-50 is better. The only practical way to lower CYA is to replace water.
The other issue is that you said Ch of 6.0, which I assume means chlorine. We tend to use either TC, when measuring total chlorine, or FC & CC for free chlorine and combined chlorine when measuring them separately. Ch is too easily confused with CH, calcium hardness.
