Esoui.com is where you want to head for add-ons. LOTS of people use minion (myself included) and it's generally really good. Some add-ons don't update well with it, but you will figure that out and can just manually update those ones. To be honest, I don't care for updating through minion, but I use it so it tells me what add-ons have been updated.. then I head to esoui.com and update them manually.
