1) If I am interpreting you correctly the hose fitting that you are refering to is the crankcase breather spout. On later cars, it connected to the airbox to allow crankcase vapors to be sucked into the carbs and crankcase condensate to trickle back to the crankcase. Many that remove the airbox forget about the important function of allowing the condensate to return to the crankcase. As these vapors are combustable, it should definitely be connected to something.
2) I believe you are talking about the charcoal canister to carb lines. The line runs from the carbon canister to a tee and to the flange on the carbs. It is to suck in hydrocarbon vapor that has collected in the charcoal canister when the car has been sitting in the sun. There should obviously be a line from the canister to the fuel tank.
3) The vacuum unit is actually a vacuum retard. It normally has a small hose connected to it and then to the center of the intake manifold. Most vacuum diaphragms are no longer any good, so at the minimum you should make sure the vacuum port at the manifold is capped. You can test the vacuum diaphragm by trying to gently blow or suck (with your mouth) through a tube connected to it. If you can then the diaphragm leaks.
The knurled knob is a "fine" adjustment for timing.
A parts manual really helps when trying to figure this stuff out.
