Grumpy_Mike:
I would put a place for a 10uF capacitor on each board where the power goes in. However you will probably not have to fit one on every board just one on the first in the chain and the last.
Might add one to each... Just because I order them 10ps at a time. 
What about the connections? Can you see anything wrong there? Been over it multiple times, think I got it right...
