Yes, the other morter is the EFSS mortar.

In addition to the EFSS, do the Marines plan on equipping the LAV 81mm mortar with the 120mm mortar? I always heard that they were disappointed with the 81mm mortar since it was so light. Thanks

That has been the plan from the beginning (Dragon Fire II was specifically tested from within the LAV-M chassis). The interesting thing was that at least during development the system was designed so that the complete trailer could be moved inside the LAV-M chassis, allowing for no need for a LAV specific system. That way the system could also be operated independently of the vehicle if for some reason required.
