CISCO Wireless Control System Software

Has anyone experience with CISCO Wireless Control System Software. I am in process of installing a 802.11a/b/g network for both campus utility as well as experimentation / play around purposes using 1240 series Access Points. I have a limitation that i dont have access to router. Rather, Data from router drops at a switch from which there are direct links to APs and servers etc (according to my info atleast). I want to get statistics of the network (i.e wireless network/APs/traffic etc). First, Do i need a CISCO wireless network controller (like 2000 or 4400 series) for this to work in conjunction with Wireless Control System Software or software can work stand alone without controller, and still provide stats etc... Secondly, i cannot plugin APs directly to Controller (which should be standard practice as per network architecture shown in CISCO site and my understanding). Can i plug in both controller and APs, as well as WCS Server and still get control on APs through controller and WCS. I can elaborate further if you want more description. I would appreciate good responses. thanks
