Virtually anything you could do to the car will make the 'ride' worse. The exception would be replacing the springs with a lower rate, longer length, and slightly stiffer shocks. This you are unlikely to find.
However, you can keep from bottoming out, and that might improve your golf-course approach shot. If your ride height is lower than spec, replace the springs. Replace the worn shocks with standard Bilsteins, and that should help as well. Check all suspension bushes and subframe mounts for wear, and replace as necessary.
As a side - if your shocks are completely shot AND you are riding on the suspension stops, replacing the shocks won't help to speak of. If you can feel SOME compliance in the suspension, then just new shocks may help.
