Well, staying away from fast food is a fantastic start. Ditching the heart stopper for breakfast is another good start. The snacks on your list are all loaded with sugar, so you may want to look into other snacking alternatives.
As far as things to eat for breakfast, fruit in moderation, egg whites (no butter, cheese, heavy salt or ketchup...)....try pepper, Tabasco sauce, low fat cheese in moderation, etc with eggs whites. Cereal bars (like South Beach diet cereal bars), protein shakes, smoked salmon, slice of low calorie whole wheat toast, and I know there's more I'm forgetting but that's off the top of my head.
As far as dinner goes, again, a protein shake could be used here, lean deli meat sandwiches with mustard, lettuce, tomato, etc on low calorie whole wheat bread, baked/cooked/grilled chicken breast with your favorite healthy seasonings....there's even a 10 calorie/serving BBQ sauce on the market that's pretty good. Baked Fish, whole grain breads in moderation, fruit in moderation, vegetables, tofu (if you're into that), 96% lean ground beef and low fat shredded cheese with hot sauce to make tacos with whole wheat low net carb Mission tortillas, and the list goes on and on, but you get the idea.
From seeing your eating list ideally you're going to want to up your protein intake and drop your carbs intake and fat intake as well.
