I keep my SWG ticking over without testing it- although one day I will get a salt test. I rely on my SWG telling me when it needs a top up of salt and don't worry about it other than that.
You have a good plan - just now concentrate on maintaining your FC for your CYA (about 60), I'd work on your pH being 7.6 which is good and start bringing your TA into range as you have mentioned with adding acid and aeration.
If your CH is 50 then you want to start adding some calcium to bring that up as well. Once that is all sorted then I would look at adding a bit of CYA to bring that up a touch to the recommended range for SWG pools (70 or 80)
