Questing essentials help

Hello Wow community!! Im wanting to know some more about questing along main story lines and things. like gear/cosmetic, mounts. ect. I want only the essential almost barebones important quests, questlines, and information on how 2 filter all this silly stuff while getting setup for the real end game. Though I prefer pvp, i sometimes do pve. but if i can achieve my wishes i would be doing more across the board. Please Help friends???
