3.46 diff would actually decrease your 0-60 time, because you cannot achieve 60mph without shifting to the 3rd with the 3.46 diff... It would improve 1/4 mile numbers though.
LSD doesn't have any effect on linear acceleration.
Stickier tires would help a great deal, since at the time of take off, friction is the dominant force to get your car going rather than its horse power or differential.
