Well, you didn't mention your budget, but probably the best bang for the buck upgrade is exhaust or gears.

Check what gears you have, I'll assume 2:73 or 3:23. If so , you can pick up a used rear with 3:42 gears for cheap $300-$500 that will help your excelleration and pick up about .3 without impacting gas milage or driving manners. Allot of people say to go with 3:73s or 4:10 but if you don't have all the supporting mods and you really want to stay a daily driver 3:42 are a good in-between gear set. And you'll need reprogramming as well.

Headers will give you a good gain as well, but will cost allot more.

We just did a LT4 springs and 1.6 rocker arms install (no cam) and there was a slight gain as well. I think the new springs were more of a help in the upper RPMs then the rockets may have been?
