Homebrew PCBs

Hi Marc & Mark,
I saw Marc's question marks on the same couple of wires I need some 
clarification on. I haven't seen any resolution yet, and wonder if these 
wires should  be cut back to the connectors, left floating, or something 
else I am missing?
Below is my hookup chart. Is there anything that is incorrect, or needs 
adding?
