Nice car man!... But as for the mods, I would definately go with 4.10's and a short-throw shifter (preferrably MGW or Steeda).
They say 4.10's tach a lot higher on the interstate but they really don't. I have 3.73's in my car right now, but I drove a good friend's 02 GT 5-spd with 4.10's on a 45 mile interstate drive to my house and it barely tached any higher. Not enough to even make me think about keeping the 3.73's
