I believe that GEOMETRY refers to the lewis structure without considering lone pair electrons. SHAPE refers to the three-dimensional structure with lone pair electrons included (all the orbitals). For example, the GEOMETRY of water is bent (because the electrons don't count for the GEOMETRY) and the SHAPE is tetrahedral (electron lone pairs are included). Hope that helps.
