Install Minion first and you can search for and download add ons from there. Dolgubon's Lazy Writ Crafter is a must have if you do daily writs. For trading, look into, Tameriel Trade Centre, AwesomeGuildStore, and Master Merchant. HarvestMap is good if you farm for materials.
It looks like you are playing on Playstation. Addons only work on PC. Just saying.

CROWN CRATES: It doesn't affect gameplay, it's not mandatory, it's cosmetic only. If it helps to support the game and ZOS, I support it! Say YES to crown crates.
My advice is to wait and see which addons you need, or want. There's a lot of things other people list as 'must have' addons which the game is unplayable without which I'd never use (including some I installed, and then deleted because I really was never using them) and others I would hate playing without which many other people have never even heard of.
As a result my approach is to just play the game as-is and then when something is bothering me, or I start thinking there must be a better way to do it I go looking for an addon to help with that situation. It means I only download (and then only have to update and manage) addons which are actually useful to me.

another quest marker--this will color the icons for quests like red for zone story quests purple for turn in green for side quests etc etc
beam me up--theres also a guild for beam me up but isnt required..get into a large numbered guild and you can use those people to teleport all over the game world for free
map pins to show you things on your map
also zygor questing addon..so this is no longer supported but the original part of the game is listed in this addon. you select a zone you are in and it will give you an arrow to follow.. similar to a waypoint addon for WoW. beware though..some zones have 800 wps..may not be much but when you want to just finish a zone, it seems to go on forever. each zone goes over side quests, main quests, skyshards and mage books. if youre interested in doing everything.
