Really, all of you guys have problems with this stuff; it's fairly easy.
As far as the exe files go, they should be in the folder that you appears when you download a file. Just save it to your desktop to start out with to make it easier to find, then double-click on what you just downloaded and there should be a folder within that which has the exe. Or you could just look at the readme once you have a file downloaded.
The game date/base folder is pretty simple to find as well. Do this:
-Click on My Computer
-Then click on Local Disc (C)
-Then click on Program Files
-Then click on Lucasarts
-After that there should be a folder for every Lucasarts game you have.
-So click on the Jedi Academy folder
-Then click on Gamedata
-And finally click on Base
Move the exe file into the base folder and you're done.

Dont extract them. When you download the .zip of whatever skin, inside it there should be a .pk3 file, shove that in the base folder, then run JKA and play. You dont need to take any files out of it, just keep it as a .pk3 file.
