New Player and a Little Overwhelmed

Hello! I am brand new to ESO. Just started a couple days ago in fact. I did the little tutorial area, and am moving on to Stonefalls. As the title says I am a LITTLE overwhelmed right now with everything. So I was looking up some things online to help and it really didn't help, so I thought I would ask here! If anyone has a minute to help a total noob out that is :D 1) I am really confused on builds tbh. I played TES games in the past and I adore the Dark Elves. But I really want to play a mage build, and I am leaning towards Necromancer. But I keep finding builds suggesting using either Bretons or High Elves. Will choosing Dark Elves really hinder me from doing high level content later? I don't know how min/max this game is tbh... 2) I noticed an Add On section, and Im not sure where to get Add Ons and which are really that helpful or not. I just kinda want things to help give me more direction on where to go and what to do. So far I've just been ignoring everything expect the main quest marker lol 3) I've been putting a lot of skill points into crafting so my gear doesn't suck. But it feels like there isn't enough skill points in the world to keep up with everything. Does that get better later? Or is this a game where I need to have a dedicated crafter and then my PvE character because there isn't enough skill points to go around? I don't want to use them and find out that I am now stuck being helpless in a fight, but able to make some sweet armor... I would rather not be dying but still styling. Any help would be VERY appreciated. There is a lot going on at once while I was playing and I am really enjoying the game. But I feel very confused and am just running around hitting things like a angry toddler.
