Where can I find a completely in depth guide to Final Fantasy XII?

I mean TOTALLY in depth, to the point of seeming cheap. I keep on messing up (being too low level, missing opportunities for side quests etc.) I want a free online guide that for example tells what licenses and gambits to give each character, when to do which side quests, and what level to be at by a certain point. I'd also like to be able to access it through iPod touch so probably not ones relying on videos.
