The idle RPM and software updates are done using SDS. I don't know if independent shops can raise the idle with the equipment available in the aftermarket. I'm almost certain they can't do the software update. As far as worn parts, engine mounts would be a good place to start checking. I'd also look closely for any A/C or power steering lines that may be touching other components. This could definitely transmit noise/vibration throughout the vehicle. The belt tensioner should be checked as well. Good luck
