1) Wait for a couple of weeks before using the ssh xbian-config clone option, as I believe there is a bug in it.
2) Your USB drive will be available as /media/[Name] or Random Letters if it was formatted without a name and /dev/sda1. Doing df -h will show it's mount point.
3) FAT-FS error. This can be ignored.

However you seem to be checking the wrong drive. The FAT-FS is the /boot directory on /dev/mmcblk0p1 not /dev/sdb1

If you want to use the USB drive to boot AND store your movies on, then I would not recommend this, as if you have a system crash, you could loose all of it - better to keep them separate.
