But I?ve got a couple of questions?.Hope u guys can help me

I don?t really know which world I want to choose, and I?m also thinking about my class?
One thing is for sure, that my first char will be a nelf warrior or a rogue?
I like pvp much but my question is that if I joined a pvp world (like bladefist eu) could I still have almost just as much fun questing like on a normal pve world then?
With that I mean that I hope that I won?t be constantly ganked by players or that (most) instances, areas or questgivers are still reachable for me?
Maybe shadowmeld is useful for not getting killed?
And then my next question will be what class I should choose?
Would a warrior be a good and fun option for a first character?
Or is it far more boring then a rogue?
Thanks in advance! (And sorry for my bad English
