You just wrote "n00b". Where to start with mods depends on your goals - the Cobb AP is definitely highly recommended (it's on my list of things to do once I get the cash), and from what I have read gives the biggest performance boost for the money. I have not heard of significant mileage decreases simply from reflashing the ECU. If anything causes a decrease in mileage, it is likely to be more spirited driving as a result of the newly unlocked power.
A lot of people, myself included, will start with free or low-cost mods, the first being the intake silencer delete + drop-in high-flow filter. It's easy, makes for a nice sound, and the car breathes noticeably better. I just installed lightweight crank and alt pulleys as well, and the car revs more freely, and seems to shift more smoothly. I like it. Anyway, as I said it depends on your goals. Have fun!
