You shouldn't nessicarily have to give them the IP of the DHCP machine...
But yeah, just disable DHCP on the devices. As you mentioned, fixed IP's for the Access Points would be a good idea. You could do this by setting a static ip on each device, or configuring a fixed IP within the DHCP server settings of OSX - you can do it by the MAC address of each network device.
