TLB, I haven't experienced either of those issues. Although I am pretty sure my compressor upper cover is hanging loose up there as well (only the lower one was removed), I get no vibrations from the area at all. Even when the compressor is running, it appears as quiet as before, if not quieter... Also, both LH and RH slider sill panels stay flush against the body on my install, something definitely looks slightly off in yours.
However...
In the past 2-3 weeks my car has developed an increasingly louder creak or squeal when I accelerate from a standstill or brake to a stop. It seems to be generating from the fuel tank area, like there is friction against it somewhere. I have dropped the RH slider in my garage as a test, and the noise has disappeared, so it's definitely the culprit. Bolts appear to be tight and the noise wasn't present for a long time after install, so I am at a bit of a loss to identify the reasons for the noise, which has become quite annoying. I will have the Tactical boys take a look in a couple of weeks.
