Hi Lisa,
Welcome to SM. One thing you might want to do is first animate the character doing a basic walk cycle. If you have a video camera, take a video of yourself doing a sneaky walk and pay attention to the way your limbs and joints interact - i.e., how the torso moves, the way the ball of the foot hits first, etc. Make some notes and apply to your walk cycle. If you decide to subcribe to SM, there's a simple stickman walk cycle video that will get you going with the basics. Otherwise, take a look in the tutorials/links forum...you're bound to find a link to a walk cycle animation tutorial. You also might want to check out George Maestri's "Digital Character Animation" books.
