How much time and money do you have?
If both were available and I planned on keeping the car for several years, I'd replace the intake manifold gaskets (upper and lower) and clean the EGR passages. If the upstream O2 sensors are over 50K miles, I'd replace them, too. If the plug wires have over 75K on them, I'd swap them out, also.
If time and money are both tight, I'd just replace the plugs.
Use either the Autolite APP764s or the new Motorcraft fine wire. Either will do well and are around 4 bucks a plug. Anything else can be addressed when you have specific symptoms that pop up down the line.
