http://ffxiv.gamerescape.com/ is about the only one I used for guides in 1.0's final months (Allakhazam's FFXIV page was hopelessly out of date).

Other than that, SE's official FFXIV pages (Lodestone naturally, finalfantasyxiv.com and the FFXIV page on SE's European website are the only other ones I've been using recently).
