There's no "official" Linux. Linux is just a kernel, a core set of software that manages a computer; every distro just adds things on top of that that are targeted to certain audiences. Fedora Core, Ubuntu, and Mandriva are targeted towards new Linux users; something like Debian are Gentoo are more powerful but a bit harder to set up. There are, of course, hundreds of other distros (no joke) out there that I'm not even going to bother to list.
You probably wouldn't need a "GNOME for Dummies" or "KDE for Dummies" book (I don't even think they mak those) because the desktop environments are pretty intuitive. However, the one thing about Linux is that a lot of things, such as installing drivers and software, are very different from Windows, and often require the use of arcane commands from the terminal. Also, updating the Linux kernel can be a real pain in the ass.
Yeah, KDE is pretty straightforward, but its nice to get familiar with the names of certain apps. I've never had to update the kernel before, since I haven't had a linux install since Mandrake 9.2.
