I'm glad you're on the road to a healthier and fitter you!
I'm not actually sure how the prizes off the Spark Wheel are delivered. Most of those I've seen people mention are physical exercise DVDs which sent out to the address they are then asked for. Have you checked to see if you were sent an email or a SparkMail with any information? Or perhaps clicking on the image where the wheel is on the start page to see if it takes you to a page with instructions?
Beyond that, you might have better results asking in the Site / Technical Help forum: www.sparkpeople.com/myspark/messageboard_t
