Does your switch have a DHCP server? If yes, then when you create that second vlan you can then assign a DHCP scope just for VLAN interface.
Create a rule on your FW for outbound DNS, either internally or to something externally like OPENDns. Since this would be a "separate network" and if you want to define it on your firewall (anti-spoofing beware) you can then create policies to block/allow certain traffic. Separately and probably a simpler route is to create ACL rules on the switchport configured for this AP to prevent/lockdown or allow activity to and from that port. I'm unfamiliar with the Dell switches, but I'm guess this is a possibility, if not with a firmware update. Cheers, Harry.
