04 Silverado crew cab Ideas?

[Chevy-Crew-SS]

I have a 04 Silverado crew cab 1500 in black, and am looking for the best ugrades (cosmetic and performance). Found this forum so I thought I would ask the members for help.
I have already installed the True flow filtersystem, re-programmed with Superchips, installed the white face gauge from a SS, New Street Scene front bumper, removed all moldings and badging, new grill, painted all door handles and mirrors, free flow convertors and Magnaflow muffler.

Future upgrades:
Shorty Headers (not sure of the Brand)
Cowl hood (reflexxtion)
electric fans (want them to be controlled by ecm)
Nelson tune
Supercharger
Trans servo upgrade (looking for the correct part numbers)

So what am I missing. I have heard of a few free upgrades for better performance, but have not found any info for them. I really don't want to do a 6.0 engine swap or anything, so I am trying to push the 5.3 as far as it will go.

looks like what you have done so far is good (accept the superchip ).you need to reload the program back into that handheld thing and sell it then call allen for a hot tune ...future mods look good and you wont want a 6.0 if you do all that stuff to your 5.3...i've been talking to allen bout a mild cam for my truck..i think that would be real good for you also..mild cam,allen hot tune and headers will wake your truck up

Thanks Bud8fan, I am still looking into a few of the adds to turn the big 285/50/20 tires I installed. Everyone seems to have a prefference on headers but I have been looking for a few people who have installed them and get there thoughts on which brand to buy.
As far as the superchip programmer, I know it needs to go. I have heard and even talked with Allen already about a tune. I would prefer to drive down when I get it so he can tune on the spot.
