How do you find this info out? And to add exact NPC coordinates do you have to actually put your character in game and open the profile creator to get coordinates or..? I'm sort of confused on how to get these numbers. :S
QuestDevTools dropdown list will have all of your characters current Quests, when you choose one, the panel on the left will show all relevant information for said quest, including its Quest Id. To get the NPCs Location and Id, target the npc in game and click one of the buttons (TalkTo, Pickup et al) This copies the XML code required to the clipboard, it's then just a case of Pasting it into an xml, or .txt document. You can also use the console for getting the required information, see here. Ofc QuestDevTools is a simpler option for new users. You can also search xivdb.com for quests, click on the appropriate quest and look at the address bar i.e: "http://xivdb.com/?quest/66758/A-Shell-to-Scry-On". The number in bold is also the Quest Id.
In a nutshell and also an issue for why there aren't many questing profiles is you need to more or less do the quest in order to capture all of the information required to make a profile to do it. With there only being one required character and you just change jobs/class there isn't a whole lot of demand to do one time quests. Though it is a draw in for prospective customers and players new to the game.
