looking at gear change

Anyone have any suggestions on which rear gear to go with.If im looking at the rpo codes correctly I have 2.73 limited slip rear.(couldnt find it stamped on the rear axel anywhere)ive read on here 3.73's are graet for acceleration but top out way to quick.If possible i would like an increase in take off but not lose all my highway mpg's and low rpm cruizing on the interstate at 80 mph.How about a 3.42 or something?Oh yeah it is a 10 bolt
