First of all you need to search and read. This all has been covered MANY times. Everyone has different opinions on everything but I know what I use and have used in the past and it has worked well for me so far.
Plugs: Autolite 764
Wires: MSD Superconductor
Oil: Mobile 1 full synthetic
Oil Filter: Fram Extra Gaurd
Trans Fluid: Mercon V
Fuel System Cleaner: Lucus Fuel System Treatment
Air filter: K&N (Im sure ill get flammed for that one)
Fuel filter: Motorcraft
Flush the cooling system
Flush the Brake system
And the most important part: Detail- clay bar and wax outside, wetsand and buff headlights, clean wheels, armor all tires, clean engine bay, vaccum and steam clean carpet, condition leather, clean windows, etc.
If those are all done at once it will make your car drive like never before.
Post pics of the progress!
