Hi Tracy! I moved your post to our new Body Image and Issues After Weight Loss forum - it's a whole new forum devoted to the questions we have about things like belly aprons, pooches and leftover skin after we lose weight. We have another thread going today that you might want to check out: Getting rid of the pooch!
Like we talked about in the other thread, ab exercises are great for strengthening the underlying ab muscles but they're not going to get rid of either fat or hanging skin. You're on the right track with your plan to do cardio. Lose the fat, work your ab muscles, and then see what - if anything - is left when you reach goal.
