Going to a real locker style 3.73 would make no difference, same gearing just no one wheel peel anymore.
And gears do not add horsepower, not sure if you read that they did.
Gears are there for mechanical advantage, they help you move out quicker or can help with fuel mileage.
The higher gear number you go the better it can be acceleration, so like 3.90's or going to 4.10's or higher. But the trade off is higher cruising rpm on the freeway. It's possible that you may lose 1-2 mpg at your freeway speeds of 70-75 mph. But you may not lose any mpg aswell, that 4.8 might be just fine with a few hundred extra rpm.
If you want more horsepower, start adding mods. Like an intake tube, headers and a really good tune can wake that 4.8 up. You'll need a tune anyway if you decide to switch gear ratio's, the computer needs to know that you did it so the transmission doesnt act up on you.

2500 to install a stall and cam. I have a Bulldog tuner. I will get a performance tune when I get the cam and stall. I was going with a 411 rear-end to get better take off
