Sorry, I haven't been exactly how to answer these, as they feel to be both basic questions and complex at the same time And I hadn't noticed that this came from a different person to the one I had responded to.

"add the kepub as an epub":

You have to add the book to calibre. There are several ways to do this (press the add button, drag-and-drop, auto add, using the command line tools, probably others). But, it basically means telling calibre about the copy of the book in it's current format. Calibre uses the extension work out the format of the book. If you have a kepub from somewhere, it needs to have the extension "kepub" for calibre to see it as a kepub. If you use the extension "epub", it will be treated as an epub. As a kepub is actually an epub with some specific code added to it, you can change the extension to "epub" and calibre will just treat it as an epub.

"use the extended driver"
That is exactly what it means. Calibre comes with a built-in KoboTouch driver. This is used to communicate with Kobo devices. The KoboTouchExtended driver (the "extended driver") is an plugin that can be added to calibre and adds function to the built-in driver. The main one is an on-the-fly transformation of epubs to kepubs when an epub is sent to the device. It is generally used as an alternative to the Kepub Output plugin (which this thread is for) to create kepubs without adding them to the calibre library.

The KoboTouch driver cans send kepubs to the device. If you have them in the calibre library, you do not need the extended driver. But, kepubs are not useful anywhere else. If you do have kepubs from another source, you can add them to calibre as kepubs. Or, you can change the extension and add them as epubs. This allows the books to be used elsewhere. But, if you want them sent to a Kobo device as a kepub, you need to use the extended driver. When the book is sent to the device, the extended driver will check if the kepub code is in the book. If it is, the book will be sent as kepub without any changes. If they are not there, the extended driver will do the work to create the kepub.

The decision on what to do depends on what format your books are coming in, and how you want to use them. Other from Kobo, books don't normally come as kepubs. So, most add the format they get them in, and either convert to kepub, or send to the device using extended driver. Or just use the epub format.
