Question Help with my setup

I am trying to learn about my home's heating system. I plan on buying a book about the general principles but from reading this site, I have seen that each setup is different. I took a few pictures of my system and was hoping someone could take a few minutes to explain the fittings and parts that make up my system and what pipes are what. I know this can be difficult just by pictures but any help would be appreciated. Here is the information that I have about the system.

Right now it is set at 190 and 160 with a differential of 10. Does this sound about right for this system?

-L8124L Aquastat
-Beckett Burner
-Bryant Boiler (model BY-411-370)
-One zone downstairs and a second zone that was added later when upstairs was finished
-Hot water baseboard heaters
-No purge valves on baseboards that I have found
-One of the upstairs pipes got a pinhole in it that was soldered closed

My main concerns are how to bleed this system since air got in through the pinhole, if any valves that should be open are closed or vice versa and the basics of how my system works.

Sorry about all the questions. I just want to learn about my system and what I can do to make it more efficient and last longer.

The fitting closest to the circulator with the boiler drain i it is your purge valve. If you turn the slotted screw type connection so it's perpendicular to the pipe (1/4 turn) it closes a butterfly valve inside the fitting. Now look at the same image and find the two fittings like it after the pipe splits off.

Turn one 1/4 turn and leave one in-line with the pipe. Connect a hose to the boiler drain in the first fitting and let water run to a drain or outside. Let water run out for about ten min.( make sure your fill valve is feeding fresh water into the boiler during this time by watching that water continues to flow with at least some force, you should also hear it filling)
When theis is done reverse the two valves after the split and repeat.
when done close the drain open all 3 valves and your system is purged.
