Hey congrats! I think pink mice look like little aliens. Weird.
Mice and rats generally make fine parents, like Marla said, don't worry about weaning.
You probably know by now that they make noises right away. (noooo! shut up you stupid things!) Sorry.
Fur comes in at around 2 weeks. Eyes also open then.
Female mice/rats come into heat right after they give birth, so if she's with a male, she's already pregnant again.
Oh.. you mean when will the babies be mature? They can become pregnant very young, but you shouldn't breed them until they are 4 months old.
And give mom one or two days alone with her babies, then you can handle them for a few minutes daily to get them used to you.
Good luck!
