Will answer what I can since I'm in the process of altering the PRC for our world at this moment actually:
1. I suspect not, but someone else may be able to answer more definitively.
2. Most of it seems to be contained in databases so I'm not suspecting any, though we haven't got to the part of testing it thoroughly. Will have to get back to you on this.
3. I can say the ECL system is pretty easy to modify. Basically it's a number in a 2da that you change to tell the system how high a given race's ECL is. For example, on our server I switched genasi to 0 ECL simply by switching a 1 to a 0.
4. It still has some bugs. It's not in a bad state, but something to keep in mind that there are still some issues here and there you may need to alter yourself. Additionally to be able to use the options available at first level you'll need to set up the ConvoCC which allows characters to take the new options after making the character. As NWN is coded, it doesn't load haks and the like immediately so this was a necessary step.
As for actually how to alter and balance it for your module I'll point you to here where I've been asking Alex Warren for help on the PRC and balancing it:
