It's better to build up your fitness level first by starting with short durations and lower intensity of cardio as well as establishing the foundation of a fitness routine that you can commit to and see yourself maintaining. Over time and as you become more fit, you can increase the duration of your sessions and the intensity. If you introduce a fitness routine slowly, you will be more likely to stick to it and for it to become a habit. Trying too much at once before you are ready can also lead to injury.
All cardio that raises your heart rate into the cardio zone (65-85% of your MHR) *works* at improving your cardiovascular health. A beginner will experience the same benefits from a lower intensity cardio routine as an intermediate-advanced exerciser will experience from a mod-high intensity routine. It's relative to your ability.
How much you eat will determine whether or not you lose weight.
Personally, I use exercise to improve fitness and be able to eat more while losing weight or while maintaining. The number of calories I consume determines whether or not I lose (and how much) or maintain my weight.
I would recommend you start with Sparkvideos. They are short 10-20 minute videos at low-moderate intensity. I think they're a great introduction to developing an exercise program for beginners. Think of them as building fitness to prepare yourself for an intermediate-advanced level video like Insanity. As though you are training for a marathon. After 6 months, you can use Insanity as a special challenge to see how your fitness has improved.

"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
