Still don't understand one thing. Sorry to sound dumb. But if I buy new replacement plugs based on what owners manual tells me will they automatically have the optimum gap we are looking for or will they need to be adjusted. Would like to just buy new plugs that are ready to be installed and don't need to be tinkered with. I'll read the entire thread again also in case this has already been mentioned. Thanks

All iridium/platinum tip plugs have the warning on them that they are fragile and shouldn't be adjusted. It's fine to do it as long as you don't put any force on the electrode tip (start at the smallest feeler and work your way up, you'll eventually get the hang of it)
About the antiseize, if you're going to do it use the copper stuff and use only the smallest dab of it. You don't want to jam up the threads.
I personally don't use any because the torque for plugs is so light. Depending on the metals and other stuff in the antiseize you might actually get some galvanic corrosion happening anyway thus defeating the whole purpose of putting in on in the first place.
Spark plugs should be considered a wear item and replaced regularly such as every 2-4 oil changes. "Long-life" plugs, to me anyway, were created as a crutch to poor engine serviceability designs.

Wasted spark is when the plug fires at the end of the the compression stroke, but also at the end of the exhaust stroke. The spark during the exhaust stroke does nothing, which is why it is called "wasted". It's sometimes easier to fire the plug every revolution. For instance, if 2 cylinders are at TDC at the same time, but don't fire at the same time, you can use one signal for both and waste one spark every revolution. Also, if you have a crank position sensor but no cam position sensor, then the ECM doesn't know if you're on compression or exhaust so it will fire both times and one will be wasted.
I would be surprised if the EB is a wasted spark design because it uses individual cylinder control and has cam position sensors, so the ECM knows which stroke each cylinder is on and they each have their own coil.
