Welcome to EM! Just remember to slow down, keep a steady throttle on the flat parts of the freeway, drive with load, and if you really want to, drive barefoot! Seriously, you'd be surprised how much more little things done to the throttle can do to the mpg's, so slip off the shoes and cool your feet!
Also, the roof-rack removal will help, although I doubt you'll be able to tell the difference (I didn't) and the mudflap removal will help the most!
Don't forget instrumentation, if you can get it, that'd be the easiest way to help improve your driving style, inflate your tires to max sidewall, and use less brakes. Throw it in neutral at red-lights, (be sure that it engages Drive first before stepping on the gas when the light turns green!) and drive when you know the engine will warm up. Running the o2 sensors in open loop is like driving with a faulty o2 sensor until it's warmed! Happy hypermileing!
