3.73 to 4.11 Ive got 3:73 gears and im not sure if i like them would 4:11 give a difference in acceleration. Is it a big enough difference worth changing them?

There's definitely a seat of the pants improvement that comes with it. It will feel much more lively on the street going through the gears, however I would base the decision on what matters most to you.
Are you wanting all out performance at the track or more interested in feel driving on the street? Depending on the power level (and I have a general idea of where you are if it's a heads/cam/intake/full exhaust LS3 build), traction is also going to be a big factor.
I'm at 450 rwhp on the motor and I swapped from a 3.90 to a 4.11 concurrent with new dual-friction clutch and lightweight flywheel and there was a big change in the way the car feels -- part of that is the gear change, part of that is the lighter clutch. The car feels very quick going through the gears and any small "dead spot" in the power band is gone. The only downside to the 4.10's is that I enjoy running road courses -- I now spend plenty of time running in 5th gear and have to do more shifting on track.
One final thought -- don't let the gas mileage argument play into your decision that much. The decrease in mileage I'm seeing with the 4.10's is nominal.

If I had to guess, probably less than .2 ET improvement. That's assuming that you can get a good launch out of the car. With the added gear, you may find a need for added suspention work/adjustment.
