Are the hoses connected to the heater core the same as the heater hoses? I am leaking coolant, and a pressure test 'revealed' a heater hose. Could it also be a manifold gasket leak?

Yes, your inlet and outlet hoses to and from the heater core would be considered "heater hoses".
You could have an intake manifold leaking coolant as well, from the manifold itself (the composite material can crack - hairline cracks...especially around the thermostat housing), or from a gasket.
