Even with the 3.73's and bolt-ons, I'm gonna say 13.0-13.1 only because you're on street tires still. The first time I went to the track in my car, it was on GY Eagle's, which are kind of aggressive for a street tire, and they spun pretty bad. That was on stock power.
As far as launching with an A4, you can go from idle right to WOT, which will cause you to spin before hooking and probably end up with a 2.0+ 60'.
Or you could hold the brake down and try to stall up before launching, which will also cause you to spin the street tires and achieve about the same 60' as idle to WOT. If you want to try this method, here's a tip. When you get to the line, slide into neutral while holding the brake, and tap the gas. You'll feel the brake pedal go down further, and it increases the braking power. Then slide it back into drive, rev up some when the lights start dropping, and get ready to go.
Or you could try this. To get over the spinning you could try going from idle, to 1/2-3/4 throttle for about a second, or until you hook, then put 'er to the floor and go WOT. I didn't get a chance to try this one at the track (guy took his grand national into the wall and we couldn't get any more passes in), but it's worked out alright on regular streets for me.
Honestly, find a good back road or somewhere safe and try different launch methods out to see what feels best to you for your current setup. There's also a lot of results if you use our search here, or just google something like "racing with automatic transmissions".
Lol just remember, do a good burnout to clean off, and heat up those tires. You'll need the extra heat on street tires.

With the NT05r's you should have plenty of traction to hold the brake and stall up. When traction is no longer an issue, that's pretty much the best way to launch because it brings you further into your powerband.
Only warning for any drag radial, it will increase the chance of busting your rear on a launch. Automatics usually help the 10 bolt last longer than manuals do, but we A4s can still break the rear easy enough if it's abused a lot.
