myrdhin - Thanks for posting your question on the forum!
You are certainly on the right track on how to configure this. Each VLAN can be made to associate itself to a different SSID. So, essentially, you would have 2 wireless networks available for users to connect to. Each wireless network will be associated with the VLAN which will have firewall rules in place to permit or deny traffic as you see fit. You will also want to keep in mind that the port that is connecting to your AP will need to be setup as a trunk to allow both VLANs to traverse.
I am not sure whether you are using NetVanta 150s or NetVanta 160s so I will provide links to documentation for both.
