I remember before the great forum catastrophe there was a thread about Non-FFXIAH sites that were particularly cool and useful. I remember a few:
Vana'diel Atlas: http://www.ffxi-atlas.com/
Maps, Mobs, NMs, Coffers, Chests, etc. (basically everything you need to know about maps)
Campsitarus: http://campsitarus.blogspot.com/
Camp info; syndicated with Vana'diel Atlas
MithraPride: http://mithrapride.org/vana_time/
Chocobo/Airship/Barge times as well as things like the 30-ish RSE timer and crafting guilds' business hours
Crafting Timer: http://www.darknessfalls.net/crafting/
Very helpful for skilling a craft (especially if you agree with direction affects synth)
Skillchain Calculator: http://magitekarmy.com/skillchain.php
Awesome for finding SCs for mobs' weaknesses. input your party members' levels, jobs, and weapons and see your possible skillchains
I also remember one called 'my ffxi gear kicks ***' (I think) where you put in your job and level then selected an attribute (ie. hp, str, evasion, etc) then hit a 'Pimp my gear' button, and it found all wearable gear with that attribute. There were many many more, but those are the few that I bookmarked.
I suggest another thread with more of these useful sites.
