I haven't ever had a problem with SD card being in any of my Kobo devices during a firmware update. Some people say to remove them, but I never have. To check the card, you pulled it out and mounted it in a PC to check for files? And it showed nothing and was readable with no problems? If so, you might want to ask in the Kobo forum. Someone else might have seen it, but there hasn't been any other reports.
As to the calibre problem, please read the full warning message and follow the instructions in it. The firmware has been updated beyond the version that the KoboTouch driver supports. The driver code has been updated, but until an update to calibre is released that includes this change, you will need to change the driver configuration to ignore the firmware check. There is no danger in doing this as there are no changes in function for this firmware version.
