Some questions (I'm new here)

Hi guys, just downloaded wotlk and I have some questions:
do I need to log in with my real battle.net account? cause I'm afraid of getting banned for that;
if I only wanna play pve which server should I choose? cause i downloaded this game to play the old wow storyline, and by playing wotlk I will make even the missions like ahn'qiraj assault right?
can I istantly upgrade my char to lvl100 to solo the raids? if yes how much do I have to pay for that? thanks for your time :)

1 - No you log in with your Warmane account. (Completely different)
2 - I believe all the realms are pvp so you're kind out of luck there. If you want to be more safe you can play as a rogue (Stealth) or paladin (Bubble+Hearth) but any priest/warrior will still be able to get you then.
