Post help with 2001 gt

i recently purchased a 2001 gt and am looking to add more horsepower and torque. i'm thinking of adding new gears first but which should i get? im thinking either 3.55 or 3.73. what kind of gas mileage will i be giving up with these puppies? what is a good brand to get? also could someone suggest some other relatively low cost upgrades to get more power. thanks.
