Here's a post on the eBook Reader going through what I have to do.

Assuming your ebooks are kindle books, you'd have to convert them to ePub/kePub anyway to read them on a Kobo. These tweaks are one-time inputs into the preferences and will take effect automatically every time you perform the book format conversion. You don't even have to remember those after the first time you set them.

Assuming your books are ePubs now, and you get a kindle, you'd still have to convert them via calibre.

You end up having to perform a conversion either way, so it's not really an extra effort for just the Kobo.

If your books are kindle books already, and you are loathe to perform a conversion, then the path of least resistance would be to get a Voyage and read on it. You have a set of wants that cannot be fulfilled 100% by any one ereader, and hence you will have to let go of one or two points.
