what andy and elfie said.
you're gonna be simmering the meats in the sauce for a coupla hours, so you want a heavy pot that's taller than wider. but you could use just about any deep pot or even a deep sautee pan. it all depends on how much you want to stir and can control how thick it gets.
) bottle of red wine helps in that matter. if it starts to get too thick too soon, add a glass for you, then a glass into the pot.
if it's too thin, a glass for you, and a small can of tomato paste goes into the pot.
