Not a smooth Idle? I'd probably start there. Aside from Cold start up, my idle is pretty smooth. That being said, I have a JB1, so that may or may not affect my idle.
As far as the sound goes, I've done some reading, and didnt really find anything that showed that it was problematic. My thought process was "stop worrying about it, drive it like you stole it, and hopefully the transmission blows up before 60k miles, so I can get it replaced under warranty" - I know this isn't very good advice, but one thing I do believe is that often times, our minds play tricks on us, we hear things, or focus on things, that others may not, even notice. Especially because we tend to be true enthusiasts, and very "in tune" with our cars. My wife always says I'm crazy, because I hear/feel things, so faint, that she would never even notice, unless I didn't point it out.
