I probably had an easier time than you will, as I didn't have to worry about drive shafts.
It's fairly simple - jack the car up (onto stands) and remove the wheel, caliper, and brake disk. Next step on the townie is to undo the pinch bolt holding the upper ball joint to the knuckle, then undo the bolt holding the sway bar link to the knuckle. Remove the upper balljoint from the upper control arm (in the lincoln, the alignment cams are here, so it's good practice to mark the position and install the new ones the same way, so the car will be closer to aligned when you take it the shop).
If you were doing tie rod ends also, you'd undo that connection now (mine were in good shape, so I left them, and didn't disconnect them from the knuckle for the sake of simplicity).
Next, you get your ball joint separator that you rented from autozone (looks like a big fork) and hammer that sucker in between the lower balljoint and the knuckle, letting it's wedge shape drive the knuckle off the balljoint.
To remove the balljoint you use your handy balljoint press (looks like a big c-clamp, also rented from autozone) to squish the old part out of there, and then turn it around and squish the new one back in (be careful here, make sure you go it correctly, you're playing with enough force to deform the control arm if you get the balljoint going in wrong).
Once you've got that all the way in there, put the knuckle back on it and tighten the bolt down. Install the new upper balljoint on the upper control arm (making sure that the alignment cams are in the same position, if relevant), and then connect the sway bar link and the upper ball joint to the knuckle, in whatever order is easiest.
Use your floor jack to articulate the suspension to make connecting the knuckle to the upper balljoint possible.
The problem I ran into was that trying to tighten locking nuts onto the studs protruding from the ball joints - the nut would do it's thing and lock to the stud, when I tried to tighten further the ball would rotate in it's socket and I'd get nowhere. This stretched out the time taken by this job a huge amount, and was really the only major setback. Eventually I got the nut so that some spare theads were exposed, I filed those down so I could put a wrench on it, and tightened it on up.
I would love to hear what tricks there are for not having to do that. It was ridiculous. I have no idea what I was supposed to do to tighten those fasteners.
And, OP, when you get frustrated (you will), go get some ice water and remind yourself that you are having fun.
