This topic that you created earlier is the best you are going to get for the core.lvl (which I see you now finished).  Anyder is one of the most knowledgable BF2 modders on this website - he took a lot of time to try to help you, so don't say you got nothing.

All of those files have tutorials on Gametoast, so read, read, and read (our BF2 tutorial section is pretty sparse).  I suggest you start smaller than replacing all those files and read about the other problems that people have had.  And remember, the search bar is your friend.
