You'll want plenty of Vitamin E to protect from the fat you are releasing as you lose weight.
I also love theanine after workouts. It helps to reduce serotonin and estrogen.
I prefer 0.7g protein per pound of your target bodyweight.
It would help to know how heavy you are now and what you plan to do to lose the weight.
You should avoid steady-state cardio except as walking. I would do HIIT sessions on an exercise bike 3x/wk and lots of walking. Walking outside will do the most for you but in the gym you should walk at a steep incline on the treadmill to burn the most calories.
You'll want to keep your muscle until close to you weigh-in date, but high reps will push more fluid into them without boosting their metabolic rate. Stick to 1-3 reps per set.
