Tim,
The solution you provided will only take care of the first task, once VLAN 8
is removed from the prunning eligible list of interface fa0/13, the switch
will continue to receive traffic for VLAN 8 regardless of local assignment
or not.
For the second task, you have to remove VLAN 8 from the VLAN allowed list on
interfaces fa0/14 & fa0/15.
