Going by memory, I think it was (from bottom-up):

Spray olive oil and a thin layer of sauce;
Noodles, ricotta mix, beef mix, perhaps some asiago and parm and mozz;
Little more sauce, noodles, ricotta mix, sausage layer;
More asiago/parm/mozz, bit more sauce, noodles;
Bit more sauce, more cheeses (lightly, including some cheddar);
Then baked, then .5 lb more mozz until melted.

Something like that
