Mod Advice Needed

ok...First off, I just ordered my Demolet Intake today (plenum to filter). Besides some basic cosmetic mods, I've got about everything on my car listed in the signature. What's the next logical thing I should do?....keeping in mind this is my daily driver. I'm steering away from nitrous and forced induction. I've had a supercharged 97, and I just don't need all that power in my daily driver. I like the sound that cams give, but I'm not sure if that's the next logical step, plus I'm a little sketched out bout opening up my engine by myself. I've thought bout headers, but it seems like the install would be pretty rough. The header bolts just seem kinda hard to get to. I've also been considering a hand tuner and a custom dyno tune, but what's the point in spending 100-200$ if I might add a few more mods in a couple months and throw off my air/fuel ratio just to have it tuned again? Please leave some suggestions.

fyi : I installed everything on my car so far except the gears, so I've got decent knowledge with hand tools. I like to do the work myself, but I'd probably pay someone else to do the install if it involves opening up the engine too much.
