You exercise as much as you want and can do safely. 3 days a week of intense exercise is fine; it's how many people start! It's important to listen to your body, though, and look for signs of overtraining. You have to eat to support your activity level, though; whether or not what you're doing is too much is not about doing 3 workouts, but eating enough to support the activity you're doing.
Healthy eating is imperative for *all* stages of weight loss. This is because weight loss happens in the kitchen... you can't out-exercise a bad diet. Exercise is important for healthy living, but it's the diet that will cause weight loss, and it's also important to fuel yourself properly for intense exercise. Undereating while overexercising is dangerous, and can sabotage your efforts.
Strength training is important throughout your journey as well. There's no reason to wait until you lose weight, and the benefits start immediately. When you only do cardio, you burn muscle as well as fat. Strength training is important to preserve this lean muscle, boost your metabolism, and overall help you look and feel better. Don't wait!
Skip the vitamins and diet supplements. If you'd like a multivitamin, get a recommendation from your doc, but they will not help you lose weight. That's a myth, and they are good for ensuring you get the nutrition you need... not losing weight. Diet supplements are a waste of money, and the only thing they make lighter is your wallet.
Rather than focusing on specific weight loss goals for your milestones, why not go with small, sustainable changes in your overall health, and establish a program you can stick with for life?
