Good place to start I think. See what he replies with.
The stone guards are a fairly simple install. I paid like $300 for mine (bought from the dealer. I could have got a better price elsewhere but wanted to make sure they were OEM exactly.) and they come primed ready for paint. I was charged $90 for a two stage paint with clear coat. A body shop can attach them with just double sided tape. There are few members on here that have had theirs attached with double sided tape only and they are holding up fine. Myself being picky about such things, had the body shop guy install them like they came from the factory. This included drilling into the under panel to install "pins" that the guard slides into. Also they came with double sided tape on the bottom, so there is also that. Long story short, they aren't gonna come off.
I would highly recommend the stone guards. They totally changed the look of my A5 for the better. I also have an S-Line front bumper on the way here in a week or so. It really isn't all that hard to convert a non S-Line car to an S-Line. So if you really want the S style, it is definitely attainable.
Guess I'm getting ahead of myself though. FIRST, buy the car.
Also, ice silver is a beautiful color. I like pretty much every grey that Audi offers. My car is quartz silver, which I absolutely LOVE. It's pretty close to Mops' old car, just a tad darker. The only color I would want more is Avus (Which is what Mops' was).
I'm still thrilled with quartz silver though.
