'06 SC 2.0T rough idle & noise

I searched the site and didn't find the answer I was looking for, so here goes:
'06 2.0T SportCombi. During a cold start (any cold start; doesn't need to be cold outside) we get an "unsteady" idle. Doesn't act like it is going to stall; and has always started right up. Next, when we shift into reverse (to back out of garage), we get a very pronounced "rattle" type noise. Only way I can describe it sounds like a loose heat shield or a broken motor mount. But, I don't think we have either of those going on.
With regard to the unsteady idle, I thought about the fuel filter, but if I understand correctly, that is integral to the pump, and I am not about to pay $400 for a sender unit and whatever labor is takes to R&R the tank unless I am pretty sure that is my problem. Plus, it seems to run fine on the road, and idles OK once it is warm.
Any suggestions? Perhaps I have two separate problems going on?
I have never replaced the accessory drive belt, which I will do (car has 114K). I did see a few posts that suggest this engine has tensioner issues, and I am deliquent on the belt service anyway.
