It's easy enough. Light the coals in a chimney, 15 minutes to light. Spread around the bottom of the BBQ, place in the pizza stone and 10 minutes later you're good to go.
I don't check my pizza. I just give it 4 to 5 minutes and then wip them out. If you want it more cooked, just add another minute next time.
Sure lifting the lid lets out heat, however the pizza stone retains heat. Taking the lid off to check or switch to another pizza doesn't really affect the cooking/temperature.
