EQLore is dead but still plenty of good info on Allakhazam
http://everquest.allakhazam.com/ and lot of maps on EQ Atlas
http://www.eqmacwiki.com/eqatlas/atlas.html
Edited: silly me, didn't realise you specifically asked about lore info, you could maybe start here
http://everquest.allakhazam.com/wiki/EQ:Lore, there is al ink at the bottom leading to what looks like an official website that is currently under maintenance and a link at the beginning leading to
http://everquest.allakhazam.com/wiki/Beta_Lore.
