Lots of good advice from people here. best thing I seen was to use a tape measure instead of worrying about a scale (your going to get bigger before you get smaller, as the muscle builds under the fat). Food is the main thing that will make the biggest difference, but I wouldn't worry to much about it, The longer you go to the gym, these things will just fall into place. I wouldn't push yourself to hard at first. You do not want an injury to mess up your routine! When you get to the gym a good way to start and end is on the elliptical.
Good Luck
