Cisco :: WLC 2504 Interfaces And Guest Networks?

I installed a WLAN with a WLC 2504 and 1140 APs. My network is configured the following way. 10.10.X.X/8. Port 1 on my WLC has the following interfaces management with the ip address 10.10.X.5 and the virtual interface. I have one secure SSID on the management interface. DHCP is done on my Sonicwall firewall. I was advised to create a second interface called AP-Manager and i have the following questions:
 
1. Do i create a new port or do I create the AP-Manager interface on the same port as my other interfaces?
 
2. Once i create the new interface of AP-Manager, will my APs migrate over to this interface?
 
3. Do i need to create the AP-Manager interface or leave all my AP's on the management interface?
 
4. Second do I need to create a services interface and if yes, on port 1?
 
I also need to create a guest network that would have the ip scheme of 172.16.X.X and have the guest authicated by level 3 web authication.
 
1. Do i create my guest interface on port1 or create a new port?
 
2. DO i need to point my DNS of the interface to the virtual interface.
