What, you're not going to replace the big sway bar insulators?
I've not done it, but I hear it's a real fun job.
The center drag link generally lasts a long time; if the boots on the joints are still good and the joints themselves are snug, then it's probably fine.
be sure to get top quality lower control arm bushings, the cheaper ones go pretty quick, and you end up ruining a set of tires.

To avoid lowering the exhaust a lot of guys take the old idler arm bolt out by grinding off the head, then mount the new one upside down, with the locking nut on the top. This might be construed as a safety issue, if the nut came loose and fell off the bolt would fall out. But with that self-locking nut, probably about as likely as winning the lotto. That being said, I lower the exhaust and do it the factory way.
