I am seriously at a loss, and any wisdom is appreciated.
Download the books by whatever method you use and then update the books in the calibre library. The simplest way to do this is to select the book in the library and drag-and-drop the book on the description area of the calibre window. This will replace that format.
To get it to your Kobo Touch, I assume you are converting it to epub. If so, just do the conversion again to replace the epub version. Then send it over like you did the first time.
Sending the book over might have problems depending on the changes in the book and the firmware version on the Touch. If the changes are minor, spelling or styles, then it should copy over and be readable with no problems on all firmware except 2.0.0. FW 2.0.0 didn't like the epub being changed and usually deleted all traces of it when you replaced it like this. The other firmware versions would usually accept it.
But, there might be a problem when you read the book if the changes are bigger. If the structure of the epub file changes, when you open it on the Touch, it might not work. It can be as simple as the TOC no longer working or causing a restart of the Touch when you open the book. The fix is to delete it and copy it over again. Because of this, I suggest you write down where you are up to in the books before you update them.
2) Lately, everytime I sync my Kobo Touch to calibre (version 0.8.65 - I know it's not the latest, but I had issues with 0.9.0), the "status" of my books that I have already read go to "unread". This isn't a huge issue-just kind of annoying. I thought I'd throw it out there. (I know this question probably doesn't belong in this thread, but I thought I'd just put the two posts together)
That means you have "Metadata management" set to "Automatic management". This is on the "Sending books to devices" page of the preferences. When this is automatic, the old driver looks in the tags column for specific tags. If a book has "Im_Reading", "Read" or a couple of other special tags, then it updates the status of the books these. If the book doesn't have the tags, the status is reset on the Touch. Changing to "Manual management" will stop this.
You should update to 0.9.1. This has a new driver for the Touch, Glo and Mini that handles this differently. There is a thread in the devices section discussing it. Plus some discussion in the Kobo area.
