www.amanda.org Useful links near the bottom include the FAQ-O-Matic
(occasionally referred to as the FOM in this group) and "the chapter"
from Unix Backup & Recovery. Start with "the chapter", it has both
a good overview and a lot of detail.

Yes, you need to label the tapes first before Amanda will
use them (it prevents you from accidently overwriting some
other tape left in the drive).

Tape is write-protected. Check the write-protect tab on the tape.
An outside possibility is that the Amanda user doesn't have write
permissions on the device, but I think that would give you a
different error.

Planner runs on the Amanda server and determines what needs
to be backed up at what level in order to use approximately
the same amount of tape each day while still honoring your
dumpcycle, runspercycle, runtapes, etc. In order to do that
it collects estimates of how much space would be needed for
different levels of dumps from each client. Basically, it
does a dump to /dev/null and counts the bytes. If you have
large filesystems you may need to increase etimeout in your
config. If there are other problems, post the exact error
messages so the group will be better able to help pinpoint
the problem(s).
