This is a loaded question as there are so many variables which are not captured by your initial post. A site survey is a requirement to even think about how to proceed in setting up the design. The fact you are asking some basic questions means you need professional services help.
I've never heard of LigoWave. I don't know where you are but the major players in the wireless space are Cisco, Aruba Networks, Meraki (Cisco company), Ruckus, Aerohive, Ubiquiti, and a few others. All of these companies have the ability to provide presales consultation to discuss general design work. They may even be able to assist with a basic topology design. Most of them either have in house professional services or a partner that can provide those services. I highly suggest you take advantage of these services.
But to answer one of your questions about layer 2 connectivity to the APs. You have to look into how LigoWave handles this. I don't know anything about them so I won't know. I do have extensive Aruba Networks experience. I can tell you none of the lightweight APs require trunk port configurations. You just create a single VLAN for the campus APs which will carry all the AP traffic back to the controller. At the controller is where the specific VLANs that are assigned to each SSID is broken out and placed onto the campus network.
