If the DFE is, for example, 8-feet, does this mean that the elevation of the bottom portion of the lowest horizontal support member/ structure that supports the above living/ habitable area must be at least 8-feet? The 8-feet is not the top of the finished floor of the living / habitable area, correct?

Yes. The elevation must be referenced to the bottom of the lowest horizontal structural member if the structure is located in a V Zone or Coastal A Zone. If the structure is located outside of the V and Coastal A Zones, then the elevation can be referenced to the top of the floor.
