Start with the simplest thing first. Pull the battery out, take it to Auto Zone and have them test it. If it's bad, replace it. If you still have a problem, pull the alternator and have it tested.

No need to mess with pulling the battery and taking it to autozone. A test light or multimeter will tell of there's voltage in the battery. It sounds like the battery was in its way out before jumping it.
Last time after it was jumped it ran for a half hour. That tells me nothing was fried.
Probably the worst is you fried the diodes in the alternator. I'm amazed that a 10 year old battery would do anything, so replace it. Then put a meter on it and see if it is charging when the engine is running. If it shows 14-15 volts, the alternator is fine.
Just jump it and go to an auto parts store (leave it running so it will not need to be jumped again). Have them analyze it for free. They will tell you if the battery is fried, or if there is a charging problem. They cannot tell you precisely what the charging problem is, but they can give you some ideas. Probably just a battery. One of my kids did this. If fried both batteries. Luckily they both had full replacement warranties, so it cost nothing.
I don't think you get full replacement warranties anymore. Not sure.
