Sam,
You're in way over your head. Please try and find a HYDRONICS professional that knows how to marry a mod/con to that old gravity system.

You've got quite the project here so you're going to have to do a lot of homework. You can then get the ball rolling by doing some of the prep work and a rough design. But Ironman is right. you really should have a Hydronics expert visit and offer you some input.

I don't know what Albany has for rules to do propane work. Most areas require a licensed company to do the gas connection to the boiler, venting, combustion air and start-up. A DYI install that causes an incident will not be covered by insurance.

• Third, and finally, with regard to calibrating the boiler: we’ve read about combustion analyzers and gas manometers but aren’t sure that they’re worth the price, given that we’d really only be using them once. Are there cheaper ways to calibrate the boiler and propane systems?

The "cheaper" way is to hire a pro who has the needed knowledge, equipment, and is experienced with your kind of project. Every once in a while you will find a contractor who will allow some DIY to cut your cost. BUT DONT MESS WITH STUFF YOU HAVE NO BUSINESS DOING.

If I might substitute 2 words to clarify the importance of your query.

• Third, and finally, with regard to calibrating the Explosive: we’ve read about combustion analyzers and gas manometers but aren’t sure that they’re worth the price, given that we’d really only be using them once. Are there cheaper ways to calibrate the Explosive and Dynamite systems?

Are you going to be sleeping in that building?

You need to understand how the system works, you can't just hook up pipes and hoe for the best. You need to do a system design before you start installing anything.

The information is all in here if you read and comprehend enough of it:
