Hi Mourad,
As Primoz mentioned, most part of the configuration will be done on the wired network.
And about your last reply...the guest and corporate users will get Ip address based upon the VLANs that they are part of. Please ensure to connect the APs to Trunk ports tagging the VLANs you want for the SSIDs. Also, I think it will easier to have two different IP scopes on the same DHCP server instead of having two DHCP servers which may need more configuration.
HTH,
Rahul
