It will make a very, very small difference. EPA says a 100 lbs reduction is worth 1-2% improvement in fuel economy (though they don't say what kind of car that's based on).

I think the very first step, if you haven't done already, is to start logging your fuel consumption. You need to know where you are now to know whether you're improving or not.
