What you're doing sounds good. Some use pizza stones or steel. When I make a round, I use a pizza screen under the dough.For us mere mortals with just a gas over, does anyone have any basic tips?
I always heat the over for 15 mins at max temps & just put it straight on the oven grills without a tray. Seems like getting the dough thoroughly cooked while slightly crispy is the bedrock of a great pizza for me
Dough is key and there are good recipes here.
