Hehe.. Those things to the “left” are the coil packs, you don’t need to mess with them. Your plugs are on the other end of those wires. Spark plug changes aren’t bad on GPs. What you heard about rocking the engine is a technique that allows better access to the rear (3) spark plugs. You rock the engine by un-bolting both of the upper engine mounts (most ppl call them dog bones). Then hold the engine rocked forward with a strap or use the secret extra mount notch.

And to answer your question, you’re half loosing it.
People just like to complain, changing plugs is dang near as easy as changing a tire.
