Need help connecting Mac pro, 2mtp av usb, 24 i/o & 896

[electrobot]

I have just added the pci-e 424 card and 24 i/o to my setup and I am now confused on proper setup.

I have 2 mtp av usb networked and are set as the word clock master.
The original 896 is connected to the mtp av's as a word clock slave.
For the mean time I have the 24 io daisy chained from the 896.

Do I need to work with adat sync from the pci-e card to mtp or 896 or neither?
Is there a better way for me to connect these pieces together or do I need a word clock generator?

Any help would be appreciated. I use live, dp 4.61, and audio desk 2.
Thanks in advance.
