Correct me if I'm wrong, but I think there is no proper documentation for Gedit LaTeX available. If that should be the case, I'd be willing to help out and start writing one. In my opinion this is a great plugin and should be made available and accessible to many more people more easily.
Let me know if you want my help, and if yes, how I can get in contact with you guys.
please to refer to the Gnome 3 version of the plugin at http://git.gnome.org/browse/gedit-latex, the guys would appreciate every kind of help there!
