.Pak help

Hello, I have recently picked up development on Aion servers an just had a few questions about some of the stuff. I have ran 2 other servers an I plan to make this a third but as I just wanna see if anyone can help me with this little problem I am running into right now. I am currently tryin to unpack the .pak files to be able to edit them an make certain things available to VIP members. I already figured that you probably need a python code to do this but I have attempted to write a few codes an i guess I might be doing it wrong cause i can't seem to extract it. Does anyone know a better way to unpack these files to make more edits to them. Also I kno this is a bit off topic but could someone point me in the right direct of a good User control panel. I wanna be able to pick it apart an try an figure out how all of it works an I cant seem to find a good one out there an all of the good ones people want you to pay monthly for from what I can see. Any input on the subject would be very helpful an thank you for takin the time to read it. Also if I accidentally posted in the wrong section I apologize.

Thanks
