(saw this after responding in the other thread)

For the noise, sway bar bushings are common... but if it happened right after the work was done, that is strange. On rare occasions I have seen issues arise on higher mileage vehicles when they're put on a hydraulic lift for the first time in a while. Basically it maxes out the suspension and all of the bushings, so something that was on the verge of being "bad" gets pushed over the edge (but im talking about very rare occasions)

As for the rough idol when stopped, thats the IAC 99% of the time (Idle Air Control valve). Dan just did a write up i think on how to clean it... let me see if i can find it.
