Well, i had the car towed to a friends shop and i finally know what the problem is. The alternator is shot. He said it was so rusted, that it just won't turn...so that's what's stopping the starter from turning over the motor. He said he took the belt off and it cranks over fine.

I guess that's how the original battery died. I dunno if it's still good or not, I bought a new yellow top just to be safe. Hopefully this will explain some other weird problems i'd been having (dimming lights, idle issues).

Thanks everyone for all the help.
