Cool.. Thanks man

Sorry to ask the noob question here, but I just found out about the world bosses and actually stumbled upon one, The First... My question is. Do I need to find a quest for that beast or just gather bunch of people and charge like cavemen in prehistoric times? I heard someone mentioned something about autoquesting.. where is that and what is that? I'd like to know specifically regarding Dromund Kaas, since I wanna take a stab at The First boss.. thanks for any info
