if you are fairly new to EQ I highly recommend collecting bookmarks!
http://everquest.allakhazam.com/
Excellent for referencing most anything EQish. Spells...mobs...quests...items... what ever. It is of course limited if you are not a paid subscriber, but it is a piddling cost for a years sub. The "free" version still rocks how ever =) Recall though that it is a player driven information site... so it is only as good as the folks who contribute
http://www.eqresource.com/
The newest competitor to Zam. They were free, then decided to go paid like Zam. Still the free section rock. Think of it as a watered down skinny version of Zam with slightly different presentation. It can be easier to navigate for looking up tasks/mobs. It also hosts the latest map packs for the last few expansions. It is also player driven for information..so there is that... heh.

The old Toon Braggin Rights website also happens to be an excellent mob lookup site. I use this when the info I find on Zam of EQResource just is not lining up with practical ingame stuff (like where the heck IS this damn Pher....) their site sponsors a location marker for actual engagements of mobs and records them on the site's zone maps.

General "I got an EQ question" information
http://www.eqtraders.com/
For all your tradeskill questions. Zam also has lists of tradeskill recipes... but hunting them down is meh. The Trader's Corner has them in a better format, along with where to find them. Generally I use this site plus Zam to hunt down specific items needed for make tradeskill stuff.
http://www.eqinterface.com/
Site for altering your ingame user interface. If you poke around here there are some that have MQ specific code. I have dabbled in a few (to get it working on my boxes) holler if you need help.

And just some REALLY OLD EQ videos. Probably wont make much sense to you with out the background as to why they are amusing, but you can see the old style graphics of the FIRST EVER true 3D MMORPG.
First one is the classic "has anyone here seen my corpse" warning... banjos!
The second one bring Raz to mind... heh. (I wish Guild Mirage would not have hunted down and killed the other videos they did...) when CCH was a common raid stratagy. That is Chain Complete Heal (10 second cast time so you have to get a line of clerics aimed at the main tank and start a rotation so they landed one after the other) as opposed to Celestial heal... which was one of the first ever cleric Heal over Time spells =)
Last video is the first ever arena 6v6 fight. I got to participate in the serverwide competition but computer was not beefy enough and lagged out during the fight, ARGH! Still... fun to watch.
Anyways... I am babbling again. Hope some of those links help. There are of course more links on this site and each of the ones I listed. There are also plenty of class specific sites that can be very helpful.
