Swithching to a simple TBI setup would mabe a big difference. A guy here has a complete TBI and serpentine setup right now for $100. (cheap) I always run a single 3" exhaust in my 4wd Suburbans, I like the torque and the mileage has always been good. Mid length headers, and a good ignition system help too. You could have a local shop do you up a set of good heads for way less than a $1000 and use the extra money on a few other things. Lots of options out there.
