If you lose access to your switch in Central, it's probably the configuration that prevents the switch from accessing Central. Do you have a router that will connect your VLANs together? The 2530 is a L2 switch. It should have DHCP or static IP with a default route to reach Central before and after the configuration change.
It's hard to tell without insight in the actual configuration what went wrong here, but I would try to get the switch configured and managed first, verify that you have access from all the VLANs for example by putting a port in each of the used VLANs and connect your laptop to it to verify connectivity, then add the AP with SSIDs and the correct VLAN assignment. If you have a small deployment, say single AP and 10 devices, probably leaving all in the existing VLAN would work fine as well. If you do this for the first time, it may help to have someone look with you together to the configuration.
