Jaeeq, The model numbers ect. are all set by the client files. To dig into it more, and edit the client files you can get eqinside from
www.hackersquest.org I am not aware of any other tools for opening the client files. There are some for dealing with a few of the files eqinside can extract though.
Just don't ask for any of the client files, or distribute them. Utilities and instructions on how to edit the files should be fine though.
As for Race, Class, Spell lists, the admintool has txt file lists included with it. There were also a few other pdf or doc files floating around.
