Rod, we have two issues here and the first (can't mount) needs to be solved before the second (automount). The second depends on the first. If you can't mount the flash drive manually, you certainly can't mount it automatically.
So:
We've got the output from your dmesg and we know that mount -t vfat /dev/sdb1... fails. What we don't know is whether udev is creating /dev/sdb1 for you when you insert the flashcard. Please check that: ls -l /dev | grep sdb should provide the relevant output.
I am assuming that udev is not providing this device. Frankly this doesn't make sense to me as mine works just fine without any special rules. But, systems are different. Based on my assumption above, you need to write a special udev rule for this card. incidentally, this will give you the oppportunity to give it a persistent name as well, such as /dev/flash or whatever. Once this problem is solved, and it mounts manually, you can look at the variety of automatic mounting solutions.
check this for udev rules: http://www.reactivated.net/writing_udev_rules.html
