Just a suggestion:

For the labor involved in replacing a boot on the suspension balljoints, you may consider just replacing the entire balljoint. They are only about $20 each, and new ones should last 100K plus. The work involved to get at these is not enough fun to repeat any time sooner.

Just boots might make sense for some of the joints in the rack, since they are easier to get at (much less labor), and somewhat more expensive to replace, depending upon which joint.
