It has been a while, but my understanding of the ZW-C is if you want to share power between channels, the jumper allows power to be shared by the channel to the left of the channel that is powered. I would probably plug a PH180 into channel A, the PH135 into channel B with a jumper to channel C, then the other PH180 into channel D.
The DZ-1000s need very little power, and work best at 14-15 volts. I would run them off channel C set to the proper voltage.
I ran PH135s and PH180s of my ZW-C, but they were not connected to the same track. I do not remember any caution against combining these power supplies (and I do read the manuals).
