There is no upper ball joint on this model.
Suspension balljoint is #15.
Bushings generally come as one kit (4 bushing 'halves') per side.
Bolts are generally sold seperately, sometimes they do need to be cut to get them out.

Removing the CAs is something of a pain.
Best bet is to do a search. This procedure has been discussed a lot.
