Can I use 00 flour or all purpose baking mix in place of all purpose flour?

Also, a-p and 00 flour have about the same protein content, so will act similarly in development of dough, texture, crumb.

00 flour can be subbed in for AP, with minimal ill-effects in just about any application I can think of. You don't want to use baking mix (without adjusting the rest of the recipe significantly), because it will have chemical leavening, some fat, and a bit of salt.
