Hey Green - You have already done way more than most. The only thing I do is move any glass away from the pool and make sure nothing can blow in. If my pool is already full, I may drain it down an inch or two since me draining it sends it to the sewer vs the overflow that sends it to the side yard.
The latest forecasts show a minimal risk of hail. While hail can certainly damage pool equipment, hail is so spotty and localized your chances of getting a damaging hail storm are slim. If you are unfortunate enough to have one of these, then you are likely looking at damage to your roof, A/C units, possibly cars and windows, etc. on top of your pool equipment. At that point you would be looking to insurance to cover the bulk of the expenses including anything with your pool.
Good luck.
