Travis, Are you routing or bridging between between the clients, APs, and your router? It would probably be worth doing packet captures and actually seeing what the traffic is. If you are routing between the AP and the router, then it is very unlikely that your problem is broadcast related. Unless you have a _lot_ of CPEs that are bridged back to the router and/or don't route on the CPE, I would be not really think that ARP is really a problem.
Broadcast storms generally are the result of 3 things, off the top of my head: 1. having a "loop" on your layer 2 (Ethernet) (shouldn't be an issue) 2. _way_ too many devices in a layer 2 "broadcast domain" (may be an issue) 3. Bad and/or malicious network programs generating too much broadcast traffic. If you control the CPE and you route on the CPE, then this can't really be an issue. You are correct on the implementation of VLANs; you will also need to create virtual interfaces for each vlan on the router and setup IPs and routing for each virtual interface. Feel free to ping me offline if you need more assistance.
