It sounds like you are doing great with Dobby and Panda and they are getting more interactive and comfortable around you, super!!
As for the touching...hmm...how do you approach them with your hands? One thing to remember is that when your babies are getting used to you, if you bring your hand down over them directly from above, rather then sort of bringing your hand toward them from a lower, palm up or a side palming position, rats (and other small critters) have that instinct of "Augggh! A big hawk/owl, etc. is swooping down to grab me!!" type thing.
It is in their nature to shy away or be threatened by the big swooping down motion of an overhead bird of prey. But you may not be bringing your hands down toward them that way.
Can you give some details on exactly what your hand positioning or body language is when you are trying to pet them?
