If you wrote the image to the card properly, it should have produced exactly the same partition sizes as before. For a Touch, that means the book partition is about 1.4GB in size. If the device is telling you it is full, I would tend to believe it. You can look at the free space on the Device Information page of the settings, or look when the device is connected to the PC (but just read the last problem).

For the external SD card, it does need to be formatted properly. That means a single, FAT32 partition. Some cards don't seem to work out of the box but formatting them again will work. And some people have found the SD Memory Card Formatter is needed.

There is also a problem with some versions of the Touch that the card is not recognised properly if inserted when the device is turned on. If you insert it after the device is started, then it is seen OK. This affect the N905, but I don't remember if it affects the N905C.

When the card is seen, the device only automatically uses it for downloading purchased books from the Kobo store if the main storage is full. It doesn't automatically move sideloaded books and doesn't use it when downloading the firmware updates.

As to the Mac not seeing the Touch, other than what you have done, about the only thing I can suggest is to try another machine. Hopefully another Mac user will come along with some suggestions.
