As NWN2 will be loosely based on the 3.5e D&D rule-set I've tracked down the System Reference Document (basically the D&D rules all compiled together for us in games like NWNs) for you all to have a looksee at:

Now obviously you can't expect all, or even the majority, of that to be in the game. But it makes good reading for a Friday night. :)
