Thanks, on my car, #10 is connected as the same place than #9 using a small hub
Well, that won't work as you can't have both advance and retard on the same vacuum hose. Just run the vacuum retard hose as per the diagram as the distributor is a mechanical advance unit (the weights are inside) and you would need a port on the throttle body to plug in the advance hose thats above the throttle plate.
The PCV is positive crankcase ventilation valve to suck the pressure out of the crankcase. If this isn't connected then the crankcase pressure has nowhere to go and gaskets and seals can leak, mostly the valve cover gaskkets.
