Holy smokes, (pun intended), I'm a newbie on here and just browsed through this thread and most of the photos. WOW, that oven looks amazing, may you enjoy many pizzas for your hard work. I wouldn't fret the dough you'll have plenty of time to experiment with that. Just today on another thread we were discussing pizza dough were I recommend using Italian Tipo 00 Flour if you can find it, it's higher in gluten which is what you want in a pizza dough.
Also, don't use a dough pin, if you do be gentle unless you are going for a very crispy flat dough. Again, experimenting is everything but I'd really track down the Italian flour that's all I've been using the past couple of years when I discovered it.
