Having to do a partial drain on my pool today due to some high CH and high salt levels. Trusting the pool store to do these readings was a big mistake. My main question is this. Once the water gets below the return lines in the pool the water is just going to be gushing out of them. Is this ok? I have no way to shut them off.

Not sure of your set-up but if I am using filter pump to pump out my water I have it set to waste and no water will come out of return line.
There is a hose bib in between the pump and the filter. When the bib is open is allows water to flow out to adjust the water level but it doesn't completely divert all of the water from going through the rest of the system.
Yes, that is fine. Just be sure to stay there to monitor the pump and turn it off when it starts to suck air. Are you familiar with the water table in your area? Are you planning to drain more than about half? Leave a foot or so in the shallow end to be on the safe side.
Not sure about the water table. I would assume it is a little high since the PB added extra pea gravel under the pool to stabilize. I am only going to drain about half anyways and refill. According to the calculator that is what I should do to correct the CH. The salt I can correct later after refilling.

Are you sure you need to do this? Does your SWG still produce chlorine when your water has high salt? Mine does
My pool water CH is 850ppm and I can easily manage it. High CH/salt doesn't necessarily require a drain. You also live in FL, so rain water dilution (overflow) is always an option.
If you do drain, I would rent a submersible pump from a local Home Depot or Lowes as they will drain your pool A LOT faster than your pool pump and then you don't have to worry about the problem you are describing.

That is a good point. The Pentair owner's manual states that it will give a high salt error at 4500 ppm but will continue to produce chlorine.
