I joined Unreliable (unreliable.guildlaunch.com), and they've been insanely helpful to me as a complete EQ newb.
Definitely second & third the p99 wiki, it's got awesome information for each class, the spells you get at each level per class, where to buy them, etc, etc. I'm not saying I bought a printer and an obscene amount of ink and paper and binders to print the whole damn thing out but...(i am totally saying that.) It's a strong piece of work.
http://www.eqclassic.de/EQAtlas/ is the best resource i've found for maps overall.
I'm usually on in the evening EST, and typically on my mage Astralux, but I reroll every other damn day because I get excited about trying other stuff. Hope to see you around in-game!
