1. Do I need to carry an extra pin, or link, or anything, or can I simply remove the broken parts, and connect two non-broken links on the road.
I just remove the broken parts and reconnect the chain. A slightly shorter chain will allow you to finish your ride and get you home. You can replace it later.
2. If I do this and remove a link, the chain will obviously be shorter, but the tension in the rear derailleur will make up for this to get me home, right?
Right!
3. If I do this, and get home on the shorter chain, do I need to go get a new chain of proper length as soon as possible, or is a shorter chain no big deal?
I'd replace it. If a chain gets to the point where it's breaking spontaneously, it's time to spend the, what, $10-30 it costs to buy a new one.
