I have four stones, all told. Two in my house, one in my camper, and a fourth that I bought for one of my kids but he beat me to it and bought his own, so the family has a spare.

In over 20 years of pizza stone use I've only replaced two. One got cracked over the years, the other broke when we tried using it on the BBQ. One and done on the BBQ experiment.
I prefer only one pizza in the oven at a time, but occasionally I mis-time my next pizza and have one ready before the previous one is finished. Rather than having the second one wait and stick to the peel

, we move the first one up and put in the second. The problem with two in at a time is that it means opening the oven more often and the temperature drops.
Wood and coal fired pizzeria ovens get hotter than 800 degrees. Their pizzas cook in 90 seconds or so!
My puny 550-600 degree temp is well within tolerance for flour based pizza. Reminder - I don't know anything about GF cooking or baking.
Because some swear by it, a couple of times I've tried freezing pizza dough but really, really dislike the results. They're harder to work with, don't stretch properly and the flavor/texture isn't up to par.
We always have pizza in the freezer, as does my daughter (I'm her family's pizza pusher-man.) When either or both of households get low, I schedule a pizza making session. Usually her family comes over and we make an afternoon/evening of it, but with the stay-at-home situation hubby & I just make them and hand off their share of the spoils.
I put full basil leaves on Margherita pizzas. I sometimes add them a minute (or less) before pulling them out of the oven, but generally put them on right as they come out of the oven. Fresh basil leaves on pizza are like making garlic bread. When you put either in the oven, someone has to be assigned to doing nothing else but watching them. They get overdone the instant one's attention is diverted.
We have basil plants in the garden, but I've never been successful at keeping them alive for very long over winter, not even as house plants. I buy two plants at a time at Trader Joe's to get us through winter pizza. I try to encourage them along to last for two pizza-making sessions. Overall success rate is about 50%. No matter. TJ always has them and at $4 or $5 for a plant, I can afford to replace them.
