New Player's Guide.

So I just bought the core rule book, advanced players guide, advanced player races,ultimate combat,and the game mastery guide. Any other essential books I may want? Also any hidden gems in the books I already have that I need to have in my first game...also just some general experience expectations because I like what the system has to offer with it's mechanical robustness and rounded approach towards the mathematical side of the game. Everything is nice and succinct, but maybe I'm missing something for a newbie like myself. What do you all think? Edit: It turns out I have Ultimate wilderness as well. So there is no way to use these materials in Pathfinder 2e?
