Welcome to PokeMMO! Some of the "new player" content/tips that has helped me is:
63 tips for beginners by Patrouski
and
Top tips for new players by DynaMMO
There are definitely a VAST array of other resources but starting with those and then checking out their other content should get you on a pretty good path.
Also if you ever wanna play/chat in game you can add me: beradical
