You have this right and wrong.

The SD card in the Kobo devices contain three partition:
  • root - holds the OS. Should be 256MB in size
  • recovery - used when doing a factory reset. Should be 256MB.
  • books - Used for all the user accessible data including the books. The size is usually the rest of the card. This is the only partition visible when the device is connected to a computer.

Of the three, you only want to resize the books partition. The others could be resized, but, there is no need to. And it would be a lot more complicated.

And do the resizing after restoring the image. Any image writing tool you use will be OK with this. And the simplest way to do this is with the partition resizing from Magic Memory Upgrade Mod. You do that after you put the updated card back in the device and have checked that it is working. Just download the file from that thread, extract the KoboRoot.tgz and put that in the .kobo directory on the device. Then eject the device and let it do its stuff.
