From my experience shedding does usually mean growth however- Leopard Geckos do shed if they are losing weight
Any time that their is a change in their body weight they will shed whether it is gaining or losing weight
If your new Leo is as healthy as she sounds from your description- i would just say that she is happy in her new home and putting on a few grams
Leopard Geckos can exist on crickets or in some cases meal worms alone-some refuse to eat anything other than one prey insect but as was said-variety is a good thing
try her on meal worms also dusted with plain calcium(no D) in addition to her crickets
They can also eat roaches,locusts,silkworms etc
just make sure that the insects that you are feeding her are gut loaded
meaning that you have kept them in a container and fed them about a week previous to feeding them to your Leo
What goes into your feeder insects is what makes your Leo healthy
it sounds like you have a wonderful healthy new pet
Enjoy her for many years to come
