If I may add: par cook the noodles for 5 minutes tops! in salted boiling water ahead of time. This will make life alot easier for you when assembling. They will be easier to handle and not fall apart. Drain the noodles in a colander and lay them out on your counter top to cool off.
Make sure you drain off excess water out of the ricotta by tipping the container upside down if a colander for atleast 30 minutes.
Make sure you lightly sauce the bottom of your baking dish.
Make sure you make extra sauce on the side... I love sauce on the side for Lasagna.
A typical pan of Lasagna should bake for approx 1-2 hours at 325 degrees.
Were going with my recipe, which to make it easier on him...Will go with the No-Cook Noodles
