Hi and welcome to 3FC.
If you are looking for inspiration and "motivation", try looking through our Success Stories here -

Here's my suggestions for getting started.
First decide on a plan. Calorie counting is what I do..it's simple and FREE. I track my calories at sparkpeople.com for FREE. You can find out more about calorie counting and other eating plans here at our Diet Central -

As for calorie intake, I don't believe there is any person(not even doctor, nutritionist, etc), website, book or device that can tell you the exact number of calories you need each day for your body to lose weight. It is about trial and error but you do need a starting ground and I suggest getting it from here -
http://www.freedieting.com/tools/calorie_calculator.htm Input your info and take the number they give you as a place to start, work it for a few weeks then tweak as necessary.
Exercise - I do DVDs and hand weights at home for FREE. Running is FREE, walking is FREE. You can also join a gym. Numerous options here. I suggest reading through the Fitness section here at 3FC -

Good luck with your goals and keep us updated on your success
