Get a roll pan to replace the big steel bumper

Raise the engines compression ratio

thats all i can think of
I would say scratch everything above and start out by coasting to stops as much as possible, reduce your cruising speed on the highway and modify your driving habits overall BEFORE you do any of the above.

The list of hypermiling techniques is a good start.

90% of your improvements will be from driving technique not modifications.
