Your workout and schedule seems fine, the cardio and high rep workouts should be great for burning calories.
More important is your diet and eating habits. As mentioned before try to get in 6 smaller meals a day. Breakfast is your most important meal, and avoid eating a couple hours before going to bed.
There are a ton of things to know about nutrition and what types of foods are great and what should be avoided.
Most people don't realize things like artificial sweeteners used in most diet soft drinks and many non-calorie foods actually promote obesity, hunger and fullness cues rely on food sweetness to regulate food intake, artificial sweeteners break this link, which tends to make people consume more calories.
I would also suggest getting a good book on nutrition or even picking up a magazine like Fitness RX for men at the store.
