Yes, read the udev documentation. You can control the permissions of any 
device node it creates using simple entries in its configuration files.

True. Device node creation is not synchronous with module loading in 
2.6, the way it was in 2.4. You should not use a sleep statement, 
though, you should use a loop that waits until /dev/zap is created, at 
least for now. To do this properly requires using hotplug-driven 
scripts, but Asterisk is not currently capable of dealing with that.
