I don't know if there's a list of ressources anywhere, but at least for fishing, there's http://en.ff14angler.com.
There's also http://www.ffxivgardening.com, or for content unlock https://ffxiv.consolegameswiki.com/wiki/Content_Unlock.
https://www.ffxivguild.com has some nice leveling guides for gatherers and crafters, but the layout is messed up for me right now.
When starting your grand company squadron, you may find http://ffxivsquadron.com helpful. If you're looking to decorate your house or apartment, http://en.ff14housing.com has got your back, but the most important tool of them all is unquestionably http://ffxivchocobo.com. ;)
