lvl 80 noob player
Welcome to GW2!!! It is a big game and there is a lot to learn and do. If your friend is on the same server as you and is part of guild, I would see if you can join his/her guild. A guild is a great place to learn/enjoy this game. I am on Ferguson’s Crossing; you can PM me if you would like. I have been playing GW2 since the beginning:) I certainly will try to answer any questions you may have. Welcome!!!
Though it may not be as good as having someone show you, and answer your questions, the Wiki is a great resource for all things Guild Wars 2. (Link above, or access in-game by typing /Wiki [topic of choice] in chat.)
Welcome to Tyria, and good luck.
You might try looking at the recruitment forum here:
You may find gw2dungeons.com handy for the fractals and dungeons, if you don’t mind spoilers about boss mechanics and that sort of thing.
qqmore.net is an excellent resource for getting better at PvP.
For WvW, ask in team chat what the teamspeak link is for your world, then meet up with a commander leading a zerg for big scale combat.
