ELI5: what tools are needed to swap out the spark plugs on my 2016 Kia Soul EX GDI 2.0L?

Full disclosure: I'm not the most mechanically inclined person in the world. While I have swapped out my battery, car navigation/audio system, ignition coils, headlghts and other lamps, this has me somewhat stumped.

I've watched a few Youtube videos on the process, and it seems quite straightforward, but the vids I've seen seem to gloss over what tools and what sparks are needed.

I know I'll need a spark plug socket, and an extended for my socket wrench; I don't have either.

I picked up some spark plugs off Amazon; the site says these are a perfect fit: they're labelled IRIDIUM ILZK7RB 11S - are these correct?

Thank you all very much in advance, I truly appreciate it!
