It's pretty much settled that if you plan on street driving 3.73's are the way to go with an A4. This being said, I have 3.73's in my car and it is not terrible on the highway. I would consider 3.90's, not sure about 4.10's as that may be a little much.

The standard answer is 3.73 gears with an automatic as Jeff said. And a 3400 to 3600rpm stall converter. Recommended brands: Yank, Circle D

i have an edge 3000 stall and stock 3.23 gears and it rips. try the verter first and see how ya like it, the gears were just a waste of money on my old car - no 1/4 improvement at all. it just felt faster lol.
