Started running how long will it take to tone my legs and butt?

Ok, im am 5'2 and right now I weigh 139lbs. I just had a baby 3 months ago and so far I have lost 49lbs. Anyways I have been doing zumba on the kinect like 2 times a week for about two weeks and I just got a treadmill not to long ago and just started running today. I ran 1.2 mi in 13 mins if I run this distance everyday and gradually moving the mile up one every two weeks is that a good workout plan? And how long will it take to get rid of my JIGGLY BUTT AND THIGHS? thanks everyone. :)
