<span style="color:darkblue">I'm sorry, but I have to agree with Steve. I figured after almost 1300 posts, you'd be beyond this, but perhaps you need to check out the n00b tutorial
? The reason you have to go through a ton of threads digging for answers is because people decide to start a new thread, rather than digging through what's there already. I mean, I've definitely seen the answers to a few of those questions just from reading all those other threads. But to answer your questions:
1. There's no list of VINs that have feathering. The only way such a list could ever be put together is if people with the problem added their VIN. And since your car obviously doesn't have it yet, your VIN couldn't be on that list yet.
2. By the same symptoms that I have seem listed a million times: growling from the tires at low speeds (especially when slowing down) and uneven tire wear are both good indications.
3. Check out the information in the TSB forum
4. and 5. Like Josh said, many people seem to have not had the problem when using aftermarket wheels, tires, and suspensions.
