juvel01, I'm 5'2" and 106 lbs. My favorite shorts are the Pearl Izumi Ultrasensor in size XS. I'm not sure if the pad would be narrow enough for you but I have no problems with chafing. When you are looking for shorts check out ebay as you can get them for cheaper. I've bought several pair, all new with tags, for cheaper than I could get them anywhere else. It's also hard to find XS on sites such as Performance and in bike shops.
