New Differential..Please Help

[LABARINTH]

Hi guys, I am swapping to a 4.6L V8 Cobra engine and a T-45 tranny. I was wondering what I should do with the rear end. Should I change the gears to 3.73, 4.10, or to 4.30? I was thinking about going with the 3.73's because everyone I talked to said they were the best. But recently I read that the 4.10's or even the 4.30's offer the best acceleration and are fine for a daily driver. The article I read said that you could drive at 80mph down the road with the 4.10's and be only at 2800rpms, which doesn't seem that bad. I'm really new to this and I want a car that accelerates hard, but I also want a daily driver. What gears should I go with?
Also, should I just change the gears or should I change the entire differential? I was thinking of Auburn Locking Differentials from steeda, but I don't know anything about it.
Please help, I have no clue what to get. I want a car that can be a daily driver, but that will also accelerate hard (I don't mind a little whiplash ).
