So far this is what I have ordered and/or planned :

Gatorback belts for SC and Acc
Intense oversized SC Tensioner pulley (My current one is dying)
GM Top-engine clean xOLF
New NGK TR55'* (Still have semi-new Spiro-pro wires on)
O2 Sensor
Fuel Filter
Supercharger oil flush
Air Filter (CAI )

Anything else that would be of use? I figure that i'll just buy some beer and make a day out of this with one of my friends who drives a GTP. I helped him do his injectors before so he owes me one

Forgot about the PCV valve, coolant flush, and new thermo too. I'm being really anal, but I figure it'll make the car run better for a while at a minimum.

get a trans flush and oil change while you are at it. Might as well get everything done at the same time.

Oh yeah, yet another question I forgot to ask, now that you reminded me : How hard is it to change the transmission filter?

And....

GO CUBS!!!!

i have gotten my trans flushed and a new filter for like ~$75 I think. I had a tranny shop do it for me, since they are pros at it. We have a good one in town.

I'd wait on the SC belt. Thats probalby the first thing you will do is drop a pully size

but he will already have the oversize tensioner, wont that accomodate for the pulley change?

That'* what I thought at first Mike, but if the pulley is smaller, it doesn't matter what size the belt is (as long as it fits). It'* still going to make more revolutions than the stock one would over the course of a full spin of the belt. The bigger pulley effectively just holds the belt tighter around the other pulleys so it grips them better.

And i'm definitely gonna drop the pulley size right off the bat, but I need a new side view mirror, struts (F and B), and sway bar links/bushings before that will happen, and those won't happen as quickly as I might like...
