I also generally find that for introductory games, it's better to put your players into an arena with NPC enemies instead of each other as enemies. Think in terms of the big arena fight in Gladiator, where the "Romans" fought the "Carthaginians." This is particularly true if they are used to playing as a team. I also probably wouldn't do magic for the first playthrough -- let 'em have fun gutting the bad guys first and then consider introducing the Wizards later.
