When you go with an aftermarket ignition system, you should follow the recommendations of the manufacturer. MSD is a business that is well known for helping people use their products correctly. They have a website and a telephone tech line ready to serve you.
If you just need to get it running until you can contact MSD, set the plug gap at .035". That's close enough.

No. On "conventional" ignition systems, i.e., those with typically a single ignition coil and a distributor with distributor cap, the spark plug boot is that portion of the individual ignition wire, running to each spark plug, that terminated the ignition wire at the spark plug and provides the wire's electrical connection to the spark plug. In newer, "plug on coil" systems that do not utilize a distributor and wires, and that are characterized by having an individual ignition coil mounted atop each spark plug, the boot is that portion of the ignition coil that pushes down over and on to the spark plug. Some few designs use a replaceable boot. Most incorporate the boot into the coil assembly.
Yes. If the ignition is malfunctioning, the spark plug will not ignite. A bad ignition module, a bad spark plug or a bad plug wire are the most common causes of that (besides a bad battery, of course).
