You're overthinking it!
First of all, Ruckus's default mode of operation is 'local breakout'. User traffic goes straight out of the AP to the attached switch, it doesn't go via the controller. In this case, just make sure the switchports attached to the APs are configured with tagged VLANs 30 and VLAN 50.
If you want the user traffic to go out to the network only via the ZD (which is the 'traditional' way of doing things by the competition), then you need to enable 'Tunnel Mode' on the SSIDs. When you do this, the AP first sends the use traffic to the ZD via the AP management LWAPP tunnel, the ZD decapsulates it and puts it back out to the network with the VLAN tag (Tag 30 or Tag 50). In this case, just make sure the switchport attached to the ZD is tagged, there's no interface to create on the ZD/AP.
