The access point i am associated with uses WPA Aes security.  I set my cpe 2-15 to WPA psk and things seem to run fine, but where can i find an explination as to all the other optional wpa and wpa2 modes the 2-15 offers? 

The main difference between WPA and WPA2 is the underlying encryption method. A Google search for wpa wpa2 differences will give you some clues. Whatever the encryption method is set to on the AP your CPE needs to mimic to be able to connect. All the WPA and WPA2 are doing is encrypting the traffic between your site and the AP so someone sniffing wireless traffic cannot decypher your communications - but nothing is fool proof. You cannot change your encryption method at your CPE if the AP does not change to the same method. Understand?

Keep in mind that the only secure method of wireless connectivity is terminating with some sort of authentication and then passing all the traffic through a VPN solution.

There are different types of authentication (802.1x) that you can use in conjuction with WPA/WPA2, if you don't want to use a pre-shared key. If the AP supports these authentication methods, you can set the CPE to associate with a username/password rather than one preshared key. These are authenticated against RADIUS at the AP level, and this controls associations.

The current AP software does not include the 802.1x features yet in the wireless security, but it will be added soon. What will the configuration of your AP look like? Will it just be an AP in bridge mode, or will it have any other configurations?
