When it was time to go home, I turned the key - nothing. I called a friend and got a jump, and drove home (about a 10-minute drive).
If it started with jumper cables, that pretty well eliminates everything except the battery and battery cable connections (i.e., starter, ignition, fuel injection are okay).
1) I need to buy a new battery.
In your other thread you said you put a battery in it. I assume that means you already have a new battery. If so, it’s either a faulty battery, a battery low on charge, or the cable connections.
2) A commercially-available battery charger will do the trick…Do I have to remove the battery and charge it sitting on the ground, or can I charge it while it’s hooked up to the car? How long does it take to charge?
First, I would measure the rest voltage of the battery (should be approx. 12.6 volts). Alternatively, see how bright the headlights are. If the battery is low, it should be slow-charged with a charger. It can remain in the car and hooked up, but first remove the cables and clean the battery terminals and cable ends where they contact the terminals. This is to ensure good contact between the charger and battery, and to eliminate poor connection there as the problem. Full charging may take hours, perhaps overnight.
If it starts after the battery is fully charged, then either the battery won’t hold a charge(= faulty battery), the battery isn’t being charged (= faulty alternator, or wiring to it), or the connections at the battery were bad. If it still doesn’t start, then the problem is a faulty battery or a poor connection on the far end of the ground (negative) cable.
3) I have a more serious problem than that (alternator, some sensor, the whole car is a piece of shit (a conclusion I’m very quickly coming to))…Any idea what’s going on?
At this point, I’d say the alternator is a prime suspect.

Gary, would they have been able to drive home if the alternator was shit?
If the battery was too dead to start the car because the alternator wasn’t charging it then there should be no power to run the car after the jump.
I’m going with the simplest thing at this point and that would be a crap battery.
