I have found that if you are careful, TB and EGR gaskets are reusable.
As you saw in the howto, I replaced all the injector O-rings. Mine all had spider cracks in them, but none were horrible. I'm not sure, but I think your O-rings might be different since the injectors for 95-97 cars are very different from the 98+ cars.
I left the fuel rail in the car, still attached to the fuel line while removing the LIM.
