90 Tank returning, looking for a what to do guide
	
	
		I am returning to the game after many years and have followed the story and hit 90.  (on Main Scenario, once more into the void).
I have full crafted gear from a buddy (doesn't play anymore).
Have just a few questions.
Outside of completing the main story, if I wanted to get into raiding, what is the best/fastest gearing path to make that happen?
What is the best way to find what guilds are recruiting tanks/raid spots?  There a discord?
Is there a best website  reference for "meta" builds/gear for classes?  
Any other info you think would be useful, that would be great.
Thanks
