/etc/rc.d/rc[0,1,2].d

Call the script K45smbmount. The K<number> part tells init that it is
a kill script to be run at shutdown. My rule of thumb is to use
/etc/rc.d/rc1.d, but YMMV.

Actually init level 6 is reboot, close though. 0 is the base run
level, 1 and 2 are always passed through  on the way up and on the way
down and the default multi-user run level is 3. 4 and 5 are left up to
the implementator and 5 is typically the X login screen run level for
linux. There is also a s or single level for single user. There might
be some more, anyone got the red book or essential SA handy?

Yes, but no one does this, I would imagine there is a reason but I don't
know it. Besides your script should be the most basic of scripts and
bourne/bash should be sufficient.
