Eating plan for weight loss and toning

I posted this in the weight loss forum, but then realized it would probably be best to post it in this forum

So when I get back to college, I figure I should probably try to lose all the weight I gained from the holidays lying around at home. A sample meal plan for a day that I have laid out has the following stats:

Fat - 25.8% (34 grams)
Protein - 20.5% (62 grams)
Carbohydrates - 53.7% (161 grams)
Alcohol - 0.0%
Other - 0.0%

Daily Sodium Intake - 2,643 mg
Daily Sugar Intake - 64 grams
Daily Cholesterol Intake - 268 mg
Daily Saturated Fat Intake - 12 grams
Daily Fiber Intake - 38 grams

Vitamin A - 157%
Vitamin C - 507%
Calcium - 91%
Iron - 86%

Calorie total = 1,129

This is with 3 meals and 2 snacks throughout the day. I want to add about 200-300 calories into this meal plan. I was thinking maybe add in a small snack before I sleep, although I could probably try to fit in some extra calories into a meal or a snack. But I was wondering if anybody had some suggestions on what to eat to improve my ratios. I'm also semi-scared of going over 1350 since it's one of those points in which I do that "all or nothing" mindset and start to deviate from my plan. I'm planning on trying to tone up a little bit, but I'm not sure if that means I should eat even more protein? I'm planning on burning about 2000-2300 calories a day from a sedentary point of 1600 (200-300 is easily walking around campus) with stats 5'3", 120 (used to be 110- yikes!) and aiming for around 112-114 pounds. Right now I'm doing cardio every day for 10-30 minutes (alternating ~1-mile days with 3.5-mile days) I'm hoping for some suggestions on weight training, and how long the durations should be for both cardio and weight lifting.

Thanks in advance!
