Its an interesting question and one I am not 100% sure about. The achievement says that as long as you complete the game without resurrecting, you should get it so I am 80% sure you should be fine without having the DLC before. I would check the achievement websites for clarity. I normally go to http://www.xbox360achievements.org or http://www.achieve360points.com. If you dont get your answer, then I would feel safer restarting as youre nearer the start :). (the pains of being a achivement whore I know, we have all been there).
