Okay......final update,
IT'S GONE!!!!!!!!!!!
The culprit wound up being the lower control arm bushings which the shop that did the work told me were a bitch to remove since they had some rusting on them. Drove it around for a while and no squeaks whatsoever. I'm gonna save up some cash to get the pass. side done soon and that way I have peace of mind.
next up........M3 subframe bushings
