2008 XC70 Rear Suspension Noises

[shoelacetrain]

The Car is a 2008 xc70 with 225,000 miles.

I have a rear driver side clunk when I drive over potholes followed by a continuous squeak...and I mean continuous. I went down under my baby's backside this afternoon and checked all my ball joints, endlinks, bushings, etc... Found what I think is a cracked stay arm bushing. I also had a friend bounce on the vehicle while I was under it and I think there's a bad strut/shock. This is my first time doing any work on this car myself. I don't want to get in over my head, but I ain't scared either!! Just wondering if there are any tips on dropping the strut out and/or replacing this particular bushing? I've looked everywhere it's deemed quite a challenge to find any info on 2008 xc70 suspension work. Thanks ahead of time anything will be useful before I just dive in.
