Not all of it at the same time, but every part of North America has at some point in Earth's history been underwater.

Yes, North America as we know it was split in two parts by a shallow sea during the Cretaceous period, 65 - 144 million years ago. This sea is thought to have been nearly tropical in temperature and very abundant with life. There are many shale and limestone deposits that are abundant in fossils from this time of our geologic past. During the late Cretaceous, the Mowry Sea and the Tethys sea merged forming the Western Interior Seaway, also called the Cretaceous Seaway and the North American Inland Sea.

A good part of it. The oil in the Permian basin in New Mexico and West Texas is from old seabed sediment.
