Legal/techy help needed

I'm putting the finishing touches to a website assignment for my current course, but I'm having some problems with licensing. I want to use some chunks of text from Wikipedia, and, this being for academic purposes, I'm doing everything properly. I've been reading about the licensing hoops I have to jump through to ethically use Wikipedia content, and I think it's starting to become less, rather than more, clear.

This Wikipedia page first says I must license my new material under the GFDL, and then implies it is sufficient to add a notice of the form:

This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Metasyntactic variable".

I can't find an "easy guide to releasing your document under the GFDL" on the GNU website, but my reading of the text of the license suggests the para above would be insufficient, and suggests instead a statement saying:

Copyright (c) YEAR YOUR NAME.
Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License".

...as well as including a full copy of the license, rather than merely a link back to the GNU site.

I'm sure some of you must know about this stuff. onebyone, I'm looking at you in particular. Please help!

(No link to the site because it's my offering for venta's advent-calendar-pot-luck, and it would be spoilery to post it now ;-)
