With what you have listed, I'd guess somewhere around 330-335 rwhp if you're an A4, or 335-340 rwhp if you're an M6. That's with a good tune though. If you can afford it, I'd add in a ported throttle body, lid, and an underdrive balancer for some extra ponies.

Streetability is hard to measure though, because it's going to be mean something different to each person.
Spend some time looking through the Gen III Internal section and do a few searches. I'm planning mine for later this year too, and researched a while, listened to videos and stuff, and I'm personally looking at the TSP 228R for streetability right now. It's a good middle ground cam for our cars. It's not obnoxious, and makes a decent amount of power.
Talk with the shop doing your tuning too. Be brutally honest in what you want out of the cam and they might be able to point you in the right direction.
