MMO beginer
I think you should look for a guild now (there’s a sub-forum here for finding guilds if you don’t want to seek one in game. It’s called “Looking For…” and it’s down near the bottom of the sub-forum lists). Because, a good guild will help you get your feet on the ground. They can help show you any of the stuff you think would be interesting: dungeons, WvW, etc… Go out and try everything. There’s no rush. Don’t think you must play one specific way, or do one piece of specific content… But, a good guild will be able to give you advice and support on the stuff that interests you, making it easier to figure out.
…as far as crafting goes, you don’t need to do that right now. Gathering all the crafting mats you come across is a good thing to do… then keep some and sell some on the TP for gold. The gold will serve you better earlier than crafting will, and then craft later when you know what you might want/need that only crafting can get you.
Good luck and good adventuring to you!

The wiki and other players will be your friend
I would honestly also say, just keep doing the personal story, and explore the world. The in game map gives you an idea of what areas you can handle, so just enjoy yourself. The other suggestions are not mutually exclusive and are also very good ideas. Find a good guild for the game types you are interested in (you can be in up to five guilds so you can check out more than one), and the wiki does help.
All good above, i can only add, harvest everything you see, save them. Don’t spend any gold, save it.
Do this and when your more confident and know what you want and what your doing then you can start.
