There are all kinds of choices to be made regarding gears and a TC package.
To save yourself some $$$, I would hitch a ride with someone (or more than one person) that has gears and TC. You might find out that you don't care for the "Feel" of a certain combination gears and stall speed as other might.
I know, I've been there. I have friends that have made bad choices as well and wish they investigated more.
3.42's are a great street gear for an A4 C5. So are 3.15's and 3.73's. But personally I hate the feel of a high stall TC on a street car. To me it feels like a badly slipping clutch. When I touch the gas street driving, I want to feel the torque of an accelerating car. Not revving and slipping.

After reading his profile I realized that we're from the same town, LOL. I offered him a ride in my car(4400 stall/3.90's). Maybe I'll let him drive it as long as he promises to be gentle.

TC more power to ground?
I agree that a TC would be a good addition.
My car has the A4 with the stock 2:73 gear and is a daily driver and logs over 16,000 miles per year. With the 2:73 it averages 31.6 miles per gallon with 87 octane unleaded on the interstate at the speed limit.
The car has these bolt-on upgrades: Callaway CAI, TTS long-tube headers (off-road), Corsa X pipe, and the stock mufflers with cut-outs, a 160 degree thermostat, and a Precision Industries Vigilante TC (street/strip 2,800 - 3,000 stall). It has not been tuned.
Once a week it gets three gallons of 93 octane fuel for use at the drag strip and runs with the muffler cut-out's open. Best elapsed time in the quarter-mile was last week 12.496 seconds, best trap time was 110.06 miles per hour. This is with the 2:73 road gear that is capable of 175 mph top speed, and great gas mileage.
In the quest for lower ET's I think the 3:42 gear would be the best for me since I value good fuel economy for those 16,000 miles per year.
Good luck with your upgrades.

I had 3.90's with my heads/cam setup and I loved it very much, in fact I was able to break into the 11's with a 6 year old heads/cam setup. Now that I have a Procharger installed as well, the gears were a bit steep so I swapped a set of 3.42's back in. It really depends on what your expectations are, if you plan on more HP in the future then you should go with a lower gear but if you will be happy (for now at least) with the heads/cam then 3.73's or 3.90's are a good choice.
