I recently got 390's in my 10 bolt with my A4 but I have a stock stall still so I can't really tell you how they would do with a stall. They are still manageable on the street and are a good split IMO between the 373 and 410's. It sits around 3000 rpms at 80.

4.10 is too much on the shot. Either go with a 28" tire, or or stay with 3.73's.
I run a 3.91 and a 26" tire, I also shift at 6500, I'd probably just get away with a 100 shot.
With the 26" tire you're only gonna stretch to about 122mph at 6500rpms. You're probably trapping about 118 now right?
*Edit, although with a cam like that I'd be shifting like closer to 6800-6900.
