Guild Wars 2

you guys are awesome. so much better than wow players. you ask them questions and all you get is “noob, just kill yourself”. Can you level your character through PVP?

Is there PVP gear like wow?

I played WoW for 6 years. Now im into GW2, which is so close, yet so different. I have a few questions.

1. I was a PVPer and loved battlegrounds and arenas. Can someone explain what I need to focus on to get on the right track to do these things on GW2?
2. I maxed out all professions in WoW. Do I need to craft things to level professions in GW2 as well? As a elementalist, which profession would be best to learn?
3. Talent points… Do I need to save them up or spend them as I get them?
