Somehow I doubt that you have the tools that are required to hold the injectors into the fuel rail but even without them you should try to pull the rail and the injectors as a unit. You are correct in that the throttle valve does not have to come off but if your engine has EGR you may elect to remove the throttle valve to give you a better shot at the EGR pipe. While you can get the manifold out without removing the fan I always pull the fan as it makes things a whole lot easier. Otherwise it is pretty much straight forward, I think that the hardest part is getting the bolts started underneath the manny for the oil dipstick tube as well as the manifold brace that is under there. If you do not know so already, remember that all of the lower bolts for the manifold go into the head first and the manifold is notched to sit on them rather than having conventional holes that they go through. This feature really helps on reassembly. If your set up has the rubber elbow that goes into the end of the manifold right behind the power steering pump make sure that you replace it while you are in there. I would clean the throttle valve out good and proper while you have it out and the throttle cable is just one silly little clip so go ahead and take that off so you can get the entire manifold out of your way.

Have fun,
