There are no records of who the first Jedi Knight was. Some say it was the Midichlorians. But the history I was taught, was that the Midichlorians were the first to use the Force. After a while a group of people started using it called Jedi. Soon, there was a disagreement and the Dark Jedi were born. They became Sith due to a species that taught them. That's how the Jedi and Sith were created…
Darth Vader isn't a Jedi Knight. His very name means that he is a Sith Lord not a Jedi Knight. From the second Anakin Skywalker is dubbed Darth Vader by Palpatine Anakin Skywalker ceased to exist and Darth Vader was born. That was also the second that Anakin was no longer a Jedi Knight, he was officially a Sith Lord. So your question is faulty.
Mods are usually contained within a .pk3 file. This file should not be expanded, but placed into your base Jedi Knight II/Gamedata/Base folder. If the file is not a .pk3 file, but a folder containing other files, then this folder should be placed in your Jedi Knight II/Gamedata folder, but the Base folder.
