Near 1 year update:

Is it really quiet?
-Yes, it's pretty awesome.

Was it worth it?
-Not really, it was a lot of work. I do like the carpet though, that was definitely worth it. The knowledge of the interior of my car was also valuable.

Do you recommend someone else do a project like this?
-If you plan on having the car forever, maybe. You'll never gain anything in resale by doing this. The carpet is nice to have brand new, but this was way more work than I thought it would be originally. Limit your scope if you attempt a project like this.
