Doing something like:

echo 1 > /sys/block/sdc/device/delete

prior to unplugging the drive will reduce messages on unplug (and will
also spin down the disk etc.).  On some kernel versions it will also
stop the kernel speed limiting the interface (if that's a concern).

Personally I use something like "logcheck" to handle this sort of thing,
and add exclusion patterns for stuff I don't want to hear about.
