Cisco Wireless Lan Controller - Config help needed

I am having trouble configuring a Cisco 2112 wireless lan controller. I am experienced with Cisco routers and switches but not with their wireless products.

Can someone give me an idea of how a configuration set-up would be?

For example, I am using an 871 router and a 2960 switch. I am setting up VLANs for management of devices as well as two different WLAN VLANs, and two other VLANs.

The controller asks for three interface addresses, an AP management address, a management address, and a virtual address. How would this be implemented and what are the purpose of the interfaces? Would I create a different VLAN for each of these interfaces?

Does the controller need to be connected as a trunk to the switch?

I have read cisco's documentation but I am having trouble putting it all together, I need to understand the concepts and how this device would generally be configured.

I think my problem is that I am looking at this device as a router or a switch but it really is neither.

I am connecting 8 Aironet lightweight APs to the this system.

The current wiring is:

router ->(trunk)-> switch
switch ->(trunk) -> WLC port 1
switch ->(access) -> each AP
