Your calculations look good, except that seems like a lot of Muratic Acid. I'd do about 3 cups to start with and then more after an hour if you need to. Do the Ph first.
Wait 30 minutes after the MA and add the bleach.
Wait an hour and add the baking soda.
Add the CYA anytime, I'd do 2-3 lbs in a sock at a time, 8 pounds is pretty heavy for a sock.
5-7 days is sufficient waiting time. 24 hrs after it has dissolved from the sock, assume it's there and start keeping your FC accordingly.
Add more bleach in a few hours, 3-4ppm will dissappear rapidly if its sunny.
