The SWG can help a little with shocking, but most of the chlorine will need to be added manually. You will want to turn the SWG off to do the overnight FC loss test.
There is some debate, but I figure that swimming is fine with FC below shock level. With CYA around 80 shock level is over 20.
With CYA that high, it will probably be almost a week before FC comes back down to normal once you are done shocking.
