Molecular geometry usually includes the lone pair on the central atom. I call this the parent shape. While Molecular shape just describes the shape excluding the lone pair on the central atom. Make sure to differentiate both if or when asked to name shape. An example I like to use is SO2. The molecular geometry or parent shape for SO2 is Trigonal Planar because of the lone pair on S but the molecular shape is bent or angular.
Looking at VSEPR notations might help. For AX4, a molecule without lone pairs, both its molecular and electron geometry are tetrahedral. For AX3E, its molecular geometry would be trigonal pyramidal but its electron geometry is tetrahedral.
What the other people said is right, I think. Usually, Prof. Lavelle says the molecular geometry first (the one including lone pairs), then determines molecular shape (the one only including bound atoms).
