If you are reading this, I am answering my own question, hopefully it helps someone else!
To replace the heater core you must remove dash, crossmember, and all that you saw in the picture (probably a 7 hour job for a mechanic, per local garage, for me a 10 hr job). Trick to removing the actual heater ductwork is to loosen the AC unit, then on the inside there is 1 bolt on upper side of unit (drivers side) and then in the engine compartment there are 2 nuts to remove about 3" below the heater core, one on drivers side and 1 on passenger side. If you are reading this hopefully this helps. Good luck in reassembly!
