Suspension is Toast!

Suspension is Toast!
My 2008 SS has 140k miles on it. Front struts and rear shocks were replaced 80k miles ago. Otherwise nothing's been replaced, so the suspension is clunky, wobbly, and arthritic. It needs total replacement. Here's what I'm assuming I need to replace:
FRONT: Strut/spring units; control arms; stabilizer links.
REAR: Shocks only.
QUESTIONS: 1) Have I missed anything? Anything else need replacement? 2) The rear is also clunky, which suggests that just replacing shocks isn't all that's necessary. But I don't see much else that can be replaced. Are the bushings for the twist-beam rear suspension prone to wear? Are they replaceable?
Thank you!

The rear bushings are replaceable, not twist beam, trailing arm.
Be aware that the ONLY source anyone has found for the correct ball joints for SS ia a complete control arm from GM.
The ball joints are different, but ALL of the parts books disregard that fact.
That goes for the struts, also. As far as we can tell there are no SS complete struts out there; you need to rebuild the old ones.

Just a FYI on rear SS clunking.
GM did a crappy job on the way the SS rear bumper cover is mounted. It's very loose fitting from the factory. Most folks think their SS has a rear suspension noise when it's just the bumper cover flopping around.
Grab it at the back and sides and give it a shake. You'll see what I mean.

Check the rear springs, there have been some that broke. The break can be difficult to see.
The front sway bar bushings should also be looked at.
The LS/LT trim levels have had intermediate steering shaft failures. Not sure if SS is prone to this.
