2008 Mazda 3 Road Trip (what mods can I do for a long trip?)

Hello Ecomodders!
My girlfriend and I will be going on a road trip from Sacramento, Ca to Georgia, 5000 miles roundtrip and we are going to drive her 2008 Mazda 2.3L Automatic. Her avg is ~25MPG and freeway gets up in the 30's.

I'm looking for some options on modifications that I can do. Generally any visual aero mods are going to be a NO because she doesn't want any visual differences to her car.

Tire PSI is at 40PSI, will increase to 50 for road trip
Have a Scangauge II in car
Will block off upper and/or lower grille
(Maybe) I'll fold the mirrors while I'm driving
There is no roof rack currently on car
There are some stock underbody panels
New 5W-20 oil (Dealer changed oil, don't know what they used)

Trying to figure out how to make a WAI on this car, have made one on truck
Maybe ways to reduce weight other than removing spare?

Any help is appreciated, we have a budget of $500 for gas and any extra $$$ will go towards Christmas!
