Why didn't you test calcium? You have a plaster pool (pebble tec), calcium levels are important!
CYA is too low for a SWG! Shoot for 70-80 ppm with your Aqualogic.
Once you get CYA in line maintain your FC beween 3-5 ppm. This will give you a 'Trouble Free Pool" in S. FL! (Are you in the Naples area?)
Salt is a bit low, Aqualogic is happiest with salt between 3200-3400 ppm
Leave the TA alone right now but test the calcium! Your lower TA might be an advantage with a spillover spa. It will help maintian a more stable pH BUT you might need to increase CH to compensate and keep the water balanced. Test the calcium!
Your pH is a bit high. Lower it to 7.5-7.6 but not lower.

Your calcium is way too low for a plaster pool. With your TA at 60 (I would leave it there for now) I would bring the CH up to around 300-350
See 'Rcommended levels"

Now here is the order I would do everything:
1. Take a deep breath
2. get a snack and a beverage (non alcoholic, you are going to need to use your mind for a little bit)
3. sit down in front of the computer and go to the Pool School area of the forum\
4. start reading everything in the order it is listed. Take your time, reread things you don't understand and if you still don't get it after a second reading jot it down so you can ask a question about it in the forum.
5. when you are done take a break and enjoy a dip in the pool. (You deserve it at this point!)
6. add bleach to raise your FC up to about 4 ppm (Use the Pool Calculator to make this easy--see the link in my signature)
7. retest your CYA to verify your reading from yesterday and add enough CYA to bring you to 70-80 ppm. To add the CYA first clean your filter if it needs it or will need it soon, with the pump running add the CYA directly into your skimmer SLOWLY (basket removed). It will get caught in your filter and slowly dissolve over the next week. Run your pump continuously for the next 48 hours then go back to your normal pump run time. DO NOT CLEAN THE FILTER FOR ONE WEEK OR YOU WILL WASH AWAY THE CYA THAT HAS NOT DISSOLVED! Test your CYA in one week. Monitor your FC levels and adjust the outut of your SWG down as the FC rises over the week. It might take a bit of tweaking to get your output percentage adjusted to maintain your FC at 3-5 ppm but you will get there and once you do you will find that your pool becomes much easier to maintain.
8. Bring your salt up to about 3200-3400 ppm (The differences you get from the Aqualogic readout and the strips are within tolerances for both of them BTW so use either number or take an average. If the two are within about 200 ppm, give or take a bit, they are reading essentially the same. The reason is rather technical and I don't want to throw too much at you right now and confuse you. If you ever get readings that differ by more than a few hundred ppm then you probably need to clean the cell.)
9. Get your calcium up to 300-350 ppm (repeat this test first just to verify that you get the same reading. Be sure to swirl the vial for 20-30 seconds between
each drop of titrant when you do this test, btw!)
Your pH is fine at 7.8 but don't let it get any higher. I would add 1 pt muriatic acid and then retest the ph after about an hour. You don't want the pH any lower than 7.5 either, btw!
10. Take another deep breath and pat yourself on the back!!!!!!!
