Haha, I'm sure trikkonceptz didn't mean anything negatively in what he said, he was just emphasizing that driving technique is the number one skill to hone when trying to save fuel.
It really depends on how far you're willing to take it. Is it an auto or a 5 sp? Depending on your body kit, you could be hurting your .cd.. Try posting a pic in the aero section and ask what people think of it as far as aerodynamics go. There are some very skilled and smart people on this site who can point you in the right direction.
Other things you can do outside of technique are to add instrumentation (scangauge), possibly a gear swap. I forget what size axle you have, 7.5" IIRC (maybe not.. something I can easily find out for you though) so there may or may not be an array of gears to choose from. Low rolling resistance tires is another thing to look into, as well as not using your A/C and removing the car of any unnecassary weight.
