Here's a pic from my 73, it's an L-82 4 speed car so there are a few minor differences, but I think it may help.
My smog pump has been removed for rebuild and my TCS switch is slightly different than yours. My input is in the front of the switch like yours but my output to the dist. vacuum advance is out the side where your vent appears to be. My vent is out the back where you see the yellowish plastic wire connector.
So here's how my connections run - looking from the front of the carb. Top right small hose goes to the Evap cannister down in the fender, the large middle hose below the fuel line input goes to the PCV valve on the valve cover then down to the cannister. In your last pic above, you have the large PCV connection right, but there is a small black hose at the bottom of the pic with a white stripe that should go to the top right of the carb. The larger black hose right next to it at the bottom of your last pic comes from the drivers side injector tube off the exhaust manifold and goes to the large hole you point out at the back of the smog pump.
My next connection is the small black hose that goes from the top left of the carb to the from of the TCS switch. This is where yours should have a T in the line and that second connection should go to the diverter valve on the smog pump.
My next connection is another small black hose that goes from the very bottom left corner of the carb (my choke pull off covers the view of that connection) and that goes to the EGR valve.
The last connection is on the left hand side of the carb, (which i believe is plugged off in one of your original pics) directly to the choke pull off. I think you have one too many T's in your system right behind smog pump.
The only other issue is the broken off vent connection at the TCS switch. Mine has a foam filter inside that yellowish connector and no vacuum line hooks to it. I would think that if yours is only a vent, you could glue or somehow strap a piece a foam to filter air that gets sucked into the vent.
Look for further input from Joel and Kstyer, but as far as no start, I doubt if vacuum lines have too much to do with that. It should start but might run really rough if you have a major leak or two. You need three things to run - gas, spark and compression. I would say either gas, spark or both are your no start issues.
P.S. - please forgive the unpainted bolt heads on my intake and t-stat housing, just R & R'd them and have had a chance to touch them up yet.
