id say for self..if your looking for noise and a bit of performance and a bit better increase of mpg.
-NGK platnium iridum plugs
-MSD 8.5mm wires (dont do that much but look alot better then stock)
-Nice cat back or full exhuast system minus headers
-Programmer, for reasons that a custom tune your limited to what octane gas you run, with prgramer you can least change the octane your running and switch back, and same with different size rubber for a more accurate speedo (custom is better, if you can afford 91+ octane all the time)
-Cold air intake eg k&n
In my 99 tahoe with the vortec 5.7, i did all that notice a difference, looked good when the hood was popped, and sounded good as well.

The basic principle to producing more power is to move as much air in and out of the engine as you possibly can.
1. Corsa Touring Cat Back - Good sound, great flow, and no drone.
2. Cold Air Intake - AEM Brute Force is great but the Spectre is identical and half the $.
3. Long Tube Headers - To further enhance exhaust flow.
4. Aggressive Cam - Takes advantage of the extra flow capacity of the exhaust and intake.
5. Black Bear Tune - To get the most out of your mods
I don't know much about the 4.8L heads. I know the stock heads on these Vortec engines flow really well. The after market plugs, wires, O2 sensors, thermostats, throttle body spacers, and de-screened MAF senseors are just gimmicks that are only going to give you marginal, if any, gain in power. Stick with OEM replacements for any regular maintenance items and spend your money where it really counts.
The computer is what ties everything together so whether you go with a programmer or get a custom tune, you should adjust your PCM to take advantage of your other mods. Forced induction is good but can get very expensive and will shorten the life of your engine.
Once your engine is producing more power you should definitely beef up your tranny. I wouldn't get a rebuilt tranny unless your's is having problems. The stock 4L60E with some mods will handle anything up to around 450 HP with no real problems unless you are constantly pounding on it.
Good luck
