Returning player - Is there a re-intro guide?

I'm coming back to this game after taking several years off. My highest level character is a 58. I am completely overwhelmed by my own inventory, and can't remember anything! I did manage to find my house, at least.

Is there a guide out there somewhere for people like me? I don't even know where to start. I debated starting a new character (I have one open slot) just to go through the tutorial again, but I'd much rather play my main.

Turns out I actually have five houses! 😂
