On my 2000 2.5 I find it easier to remove the upper intake manifold.
Once the upper intake is removed you then have access to those two coolant hoses that run to the intake and then down into the block. Make plans to replace those with 1/4 ID heater hose. Also Ford recommends replacing the PCV every 60,000 so throw one of those in as well.
My first set of plugs were ford, from the factory and I got about 100,000 before replacing. THose plugs were double Platnums. Ford apparently no longer makes double P's for that truck and recommended a single Platnum plug. I install those and replaced them at 60,000 and they looked like crap. This time around I used double platnum Autolites so hopefully they will last to 100,000.
You need a new gasket for the EGR and the upper intake when all done.
