You are correct that you can't use the desktop to add sideloads, but there is no need to. Personally I drag and drop, others use Calibre. The free books aren't on the Touch, so no need to get rid of them. A firmware update added an option on the original Kobo's to hide them, but if you actually wanted them off the reader you would have had to do some hacking. No need for any of this with the Kobo Touch (current reader).
