When you create the group, use the format "+6 month" for expiry, then 
each user will have 6 months from when you create the user. (And just 
don't set any data/time limits in the group or the user)

In the latest version you can set all the Network Settings in the admin 
interface, you can change the netmask there.

Unfortunately there is really hard to stop, even with WPA2. Your 2 
options really are advising users to use HTTPS instead of HTTP, and 
having a clause on the login page (Terms and Conditions) that all 
"cracking" activity will be reported to the police etc etc.
There are a few linux tools you can run that detect arp spoofing, which 
may also give you the mac address of the client doing the spoofing. You 
can then block that clients access totally, although that won't stop 
them trying, but if they find out they don't get any Internet access, it 
may deter them.
