I don't think you'd be able to fix it at this point and save any money than you would by driving the truck.
If the anti-lock brake light is on, it means you're probably not getting ABS protection, so you're running a risk there. I had the ABS light come on in my Impala, and had to have the brake computer replaced. That was a few hundred. You're running a junk yard moor, so there's no telling how many parts you can replace before you'll have spent as much as just buying a rebuilt motor.
If the battery keeps dying, you might also have a bad alternator. That's another part.
Try to sell it and buy something else. I'm not far from Gainesville and I'd help if I had the know how, but I'm not sure what all is wrong with your car.
