Yah, I think my lack of knowledge has started a debate. To make it worse I typed a reply and it didn't work because my cookies didn't match up. Go figure.
Anyway, to answer your question yes when I unplugged the vacuum advance the idle did slow down. I didn't check the timing before and after i unplugged it though.
Ya, I think it was decided in another thread that my carb is likely gummed up and needs an adjustment. I wont be able to do a highway drive for a while, but can take a cruise around. It won't take much for me to know if the car has improved since I first drove it. When it was a shakey slug

One more thing before moving on. When you pull the vacuum hose from the vacuum advance (when checking timing) does timing jump back and the engine slow down? If so that's good. Just want to make sure that the vacuum diaphragm on the distributor is OK.
The vacuum gauge should be hooked up to any manifold vacuum source. Since you have the vacuum advance connected to the manifold you can tee it into this hose.
Regarding the engine quitting when you put the car in gear- if you have the PVC hooked up properly and there are no major vacuum leaks, timing is set properly, and it is firing on all cylinders then it sounds like a carb problem. Assuming that the Edelbrock has a big enough idle circuit for your cam (I have no experience with Edelbrock) then the idle speed and mixture screws probably just need some adjusting. Having the vacuum gage connected will help with this.
Yes the engine needs to be warmed up and the choke disengaged to get good vacuum readings and to make carb adjustments.
