If your pan is 2" deep you will need 11 cups of batter. I would make 3 mixes and use the leftover batter for cupcakes.
I use bake-even strips and 2 flower nails in that size pan.
As for baking tips, you should probably use at least two flower nails in the pan itself, greased and inverted, to help distribute heat in a cake that size. I'd also use the baking strips around the outside of the pan to keep teh sides from baking way faster than the centre.
