3.92s to a 4:11 wouldt make much differce, im not really wanting to get **** gas mileage either, my camaro had 323s and i swapped to 456s, by by gas milage
This is incorrect. Out of anything you could do, besides maybe a SC/Turbo setup, the 4:10 gears will be most noticable. I myself have a 5.2l, and went from 3.55's to 4:10's. I know have to becareful on take off or I will break the tires loose everytime. Its almost too much. I was planning on a lift with 35's and 4:10s, but chewed up some spider gears and needed to do some work back there anyway, so the 4:10's came early. Once I get those 35's it will even out a bit better.
If you change the gears in a car with out changing the tires size, you will see a MPG loss do to your rpm range being higher. But in this case, because of the large tire diameter it will actually be closer to stock then you are now. Your motor will not have to work as hard to turn the tires the same amount, thus you might actually see an improvement in MPG.
My list of things would be as follows (in order):
1. Exhuast + CAI
2. Headers (I would do shorty headers myself, maybe even a bit of header wrap while your at it.)
3. V8 TB
4. 1.6 rockers
5. Gears (If your only 2wd, I might actually do these before the rockers myself.)
Also get rid of the resistor chip. Your motor needs a certain A/F mixture or damage can occur. As for the CAT, I have never seen any data that shows how much you gain from a hi-flow CAt or removing it altogether, so I leave that to you. It will throw a check engine light with out the O2 sensor fooler thing-a-ma-jig.
