What can happen if you don't is the software thinks it's just part of the current zone and appends its own name to the end, like you saw. That could be part of why you are seeing some of those errors as the nameserver names are wrong.
Definitely also setup the slave servers on ISPConfig3 the way that till said. You may also need to check your firewall allows port 53/tcp.
