Since you are in the moist north east, I would soak the crap out of both the bolt that goes through the control arm, and the 14mm that holds the joint to the steering knuckle with PB blaster. Let it sit for at least 1/2 an hour.
I've used inexpensive pitman arm tool (from NAPA) and pickle forks to remove the ball joint from the control arm. Since you are replacing it, damaging it doesn't matter.
Remember, after you get the 14mm out of the knuckle, to use a wedge (also known as a broken screwdriver) and a hammer to open up the slit on the inside of the knuckle. A big pry bar will be needed to pop the knuckle off the ball joint.
