You need to isolate the concrete foundation (with foam insulation)and the entire outside wall, concrete floor to the underside of the floor above, from the conditioned/living space. So it sounds like that your plan is to cover the remaining un-insulated concrete with foam. That's a good start and as long as the remainder of the outside wall is also insulated with foam you should be ok. If you have a partition in front of the foundation then that partition must have a floor to floor above vapor barrier and should be insulated as well if you live in an area with cold winters.
