I have plans to remove and replace the thermal reactors with the Bursch replacements and remove the air pump and air lines. I have no idea how I am supposed to change spark plugs/adjust valves on the driver side with the air pump in the way. I did figure out how to set the dwell/point gap despite it. Should I leave the EGR pipe in place or maybe move it to the same cardboard box as the other named parts? It doesn't seem to be causing any problems and it isn't in the way right now.

Something you might consider:
The main culprits to overheating are the thermal reactors and five blade fan. The smog pump can be removed, along with its engine compartment hoses, and you can still leave the plumbing to the exhaust ports which can be a real bear to remove. The check valve, located just below the engine tin by the pump, will keep exhaust gas from blowing back into the engine compartment and leaving the plumbing will not increase engine heat. (You might want to do a search on removing the plumbing from the exhaust head and get an idea of the PITA it is.)
Second, the erg system is relatively benign and may be left alone also, IMO. I suggest keeping the two systems mentioned because they really don't add to the overheating problem and if you ever sell the car (especially back into the Cal market) they will be needed.
