Skip the 3.55's and go with at least 3.73's, 4.10's if you plan to keep it Naturally Aspirated. I have run both 3.73's and 4.10's in my daily driver for over two years.
As far as the intake goes, on stock heads you will see a minimal gain. If you plan on heads in the near future, then go for it.
AS far as the exhaust goes, I also recommend long tube headers along with and x-pipe or Pro-Chamber, then a good cat back 2.5" system.
Do a full tune-up, plugs, wires, dist. cap, bump timing, K & N. I also suggest you invest in an adjustable fuel pressure regulator, this will allow you to fine-tune your fuel pressure to help maximize your combo.
Swap out all your vital fluids with synthetics (engine, tranny, rear-end)
Pulley's are a worthwhile mod.
With an electric fan, you'll more than likely have to upgrade your altenator to the 3G unit, something to keep in mind.
Definitely get a shifter, if nothing else it's cheap insurance for the tranny.
Hope this helps!!
