How do I behave as a new player?

HI guys! Long time Fallout player, but just picked up 76 this week. Obviously the gameplay is different. I'm not about PvP, so I have turned pacifist on. I'm making the assumption that players with vendors on their camps expect other players to wander through them. Is it rude to use other people's workbenches? I also want to now what the vibe is for getting carried through events. Do people get upset about having to drag a new player? I would also love any tips, tricks, and other community etiquette pointers. Thanks!
