I would say learn to burn your own chips to get the most out of the mods you have but if not that then intake and headers. You could do the ultimate TBI mods too since its free.

Second that. Gears or subframe connectors would also be nice. Either of those should be your next mod.

You need to visit the DIY PROM board and get ready to read. It is very simple once you know what you are doing. It just takes practice. It is way to hard to get into detail here. Since you are in california with the smog ***** you need to reatin all of your emmsions and get an exhaust that supports that. There are tons of sytems out there and quick read through of the exahust forum will give you some ideas. I would not even consider a cam if you do not tune it right. You will never pass emmisions with a cam swap and a poor tune.

You sound screwed (stupid smog laws)
Go the DIY Prom board to learn about burning chips, noone can really just tell you how to do it.
Why afraid to do the ultimate tbi? If your real nervous about screwing somthing up like me and cannot afford to have your car down for a few days, get a tbi off ebay, modify that one then swap them, thats what I plan on doing (as soon as I can find one, you would think there would be more on there). You can do the open element filter too.
I think you can get hooker 2055 headers with the AIR fittings.
As far as intake manifolds go, I don't think the do a heck of alot without other modifications, but i'm not sure on that one.

Damn, ive been beat to it

I have the 2055s and I would rather pay the extra $100 and get the Macs seen here:

I got jerked around from mac when I tried to order so I hope you have better luck because those are damn nice headers.

2055's do come with AIR fittings.
you really do need headers, then prolly tuning.
