Ron, 

I would use use bridge_mapped networks and let Neutron / OVS handle everything.
When you create the bridge mapped network in Neutron you can specify which VLAN ID you would like to use by using:
--provider:segmentation_id $VLAN-ID 
This way you can map your Neutron network to an existing VLAN.
Neutron will make sure the OpenVswitch will tag the packets to the appropriate VLAN.
