Sounds like a good plan David ;
Go buy some of the four way vacuum connectors , all the Partshaus' have them , and the long hose too , then you're ready .
Overhauling the vauum pump is a good idea ~ with everything but the brake booster capped off , the vacuum should come up to 21" or so of vacuum very quickly after you start the engine .
Remember to replace the two short bits of rubber hose under the dashboard on the back of the ignition switch .
Buy a rebuilt servo before you do anything else , clean the cooling system Hospital Clean as minor bits of crud & rust are what causes the Eveil Klima I Servo Of DEATH to fail.....
I posted how to test it long ago , it's in the archives .

Thanks for the advice on cleaning. I was using some dish soap (Dawn) and warm water. I cleaned them since I took the pictures. I'll take some more later this week of the cleaned up hoses.

I'm sure that will be an adventure but hoping that if the right hose gets plugged in a few things will come back online. I'm going on the assumption that the servo is bad and will be replaced. The vacuum pump doesn't seem to suck very well as it takes a while for the brakes to get some boost. I'll hook up the gauge to it this week and see what reading I get. The brake booster was replaced and a new seal at the m/c was installed. I have a rebuild kit for the vacuum pump and may just rebuild it anyway.
