PvP servers and Beta servers any difference in PvP?Follow

Hi, I don't have beta for this game but i plan on buying WOW. I am going to ask a few questions that i would like answered please because i want to know which server to play on.

1. In a PvP server where are the locations where you can be attacked. Can you only be attacked when you are in a contested zone or red zone.(not sure about this even being correct)

2. In a PvP server is the server made that you can only be attacked by a faction if you attack the Npc. Or is that offered only in the Beta server.

3. In the PvP server can you be constantly be killed in a red or contested zone.

4. Is there special places where you can xp when your 30-60 without getting killed.

5. Does Beta servers offer PvP. Or is it only a rp server basically.

I apologize for the order of the questions and how confusing some may be. The whole reason why this is important to me is that i love pvp mmos but i want to be in a server where you can pve until your good enough for pvp, without getting killed while xping.

funny thing is after i made the post i saw your thread. sorry but i just came to the site without looking at other posts i just wanted to post.
