Guild Wars 2

Hey everyone.

I am new to playing the Guardian, and to GW2 in general. I am looking for some/any advice on what to really do. I realize however just how broad that request is.

I would like to play with a 2h weapon if it is viable. I just started playing using a 2h hammer last night, and was having a blast with that. My question(s) though are, what exactly should I be focusing on doing?

I am currently level 9. Is there something in particular I should be following while questing? I have been just following the heart icons on the map to get stuff done, but it is hard to take on numerous mobs my level if I am by myself, especially if they are ranged since they seem to have a huge aggro radius, and they will not get close to you.

Also, I have been doing WvW since I seem to be able to level in these areas as well. Is this a good alternative, or only, when I get to an area where the mobs are tough for me? Should I just grind out killing mobs for a while after doing a couple quests?

How important is the professions for me? I have not began on any of them, and not sure if I am hurting myself by not.

Traits. I realize I am not high enough to learn the first book yet, but what exactly are they for?

I am sure I may think of more stuff later, but this is a good starter. Feel free to toss in anything else you deem important.

Thanks!
