Help with progressing through the game and systems

Most of the time, I don't really feel like doing lore quests. I play MMOs mainly for the combat, progression, and grinding.

Right now I'm leveling through daily dungeons, Battlegrounds, and Dolmens (Dark Anchors), and I'm almost level 50 (currently 44).

Once I hit 50, my plan is to start farming gear for multiple builds and spend most of my time in Cyrodiil.

I feel like I'm missing a lot of the game's systems because I still don't really understand how progression works in ESO.

Can I mostly ignore things like questing, Scrying, crafting, and other side systems if all I want to do is grind PvE and PvP? Or are there any systems that are basically mandatory if I want to stay competitive in endgame PvE or PvP?
