If I could do it all over again, I may have chose to leave my stock 3.31 gears in and save the $$ spent on the 3.73's for something else.

Mine came with 2.73 stock!!! I swapped in some 3.55s and was fine with the mpg back then. With a 6 speed like what the OP has or the new stangs run, you could keep the 3.73s and still do really well!
