Hi there! Welcome to the site and congrats on turning over a healthier leaf!
For your diet.... 2 cups of water a day is not enough... its honestly not even close. I would increase that by alot and take out the diet soda as that is full of chemicals and other crap. For your meals... try to eat foods that are as close to nature as possible.. with little to no processing. This means stick to things like whole grain breads (which you're doing.. good job there), sweet potatoes/yams, oats (not the kind in the packets.. just plain oats), brown rice (unseasoned... that uncle bens stuff is usually loaded with salt and other stuff that you really don't need), whole grain pasta, quinoa, whole grain couscous, veggies, fruits, and of course lean proteins such as eggwhites, chicken, lean red meat, low fat cheese, fish, and soy.
The meal plan you posted doesn't look too bad but what if we tried something like this instead:
Breakfast: All options look good! You could add a piece of fruit there. Or you could go for something like eggwhite omelette with 1/2 cup oats.
Lunch: Pizza and burgers are honestly terrible. I would switch to maybe a sandwhich on whole grain bread or grilled chicken salad with low fat or vinegaratte dressing. Also, you need veggies in this meal. Turkey burger is a good option. If youre having it on a bun go for whole wheat and maybe only have 1 piece of bread instead of both. Might also benefit from adding things like green beans, asparagus, spinach, peppers, zucchini, mushrooms.
Snacks: Watermelon is honestly not the best choice... but better than the kit kat bar. The purpose of having snacks is to keep your metaboslim revved and keep your blood sugar stable. I actually consider everytime I eat a meal, and eat 6 meals a day instead of 3 meals and 2 snacks... this ensures that the metabolism will be firing on full speed all day and keeps energy levels stable. For snacks, you could leave the watermelon in, but add a few nuts and maybe some low fat cheese or other lean protein to this "snack" to give you a better balance of nutrients. The kit kat bar, kisses, and musketeer are really only setting you back. If you must have them then go ahead but do so after working out and don't consider those as "snacks". Instead, you could do veggie sticks, 1 boiled egg + 4 boiled eggwhites, and 1/2 an avacado, or 1/2-1 cup ff cottage cheese with a serving of nuts and veggie slices, or 1 can of tuna (if you haven't already had some) with veggies... for snacks just make sure youre getting protein, healthy fat, and some form of fibrous carb (either veggies or grains). Add water to your snacks.
For your exercise plan: that is definitely a good start. Do you have access to a gym or weight lifting equipment?
Hope this helps... Please feel free to post questions if you have any.

For dinner: doesn't look too bad... I would get rid of Uncle Ben and do unseasoned brown or wild rice, the chicken looks great, tomatoes are good... you could add more veggies in here.
