Amy, no question is a silly question and never feel you have to apologize for asking anything. All that means for us is that you want to do things the best as you can and that's a good thing
Like Caryn said, I also don't do the bath more than once. But sometimes i even use a couch or bed that is neutral territory for all of them. You haven't had anything major happen yet so I would also say move onto the next step. A good idea is to give the cage a thorough clean with vinegar water as that neutralizes the wee smell. When you re-hang things in the cage, also after a wash, try put things in different places. Like change the structure of the cage a bit so that it seems different or new to Mamma and Nibbler as well. Even wash the food bowls and put clean dry food in. Basically try get the old smells out as much as you can... then plonk them all in at the same time and either watch for a bit or sit in a room close by so you can hear if there's a scuffle (not the occasional squeak, but a fight, you WILL hear the difference)
What I sometimes do is while redoing and cleaning the cage is I put all of them into a small travel cage..so no one can run away or hide in a favorite spot.. and have them in the room with me ( only during intros mind you) then put them into the cleaned cage once I'm done if their time in the little cage together has been without incident.
I would personally get them happy in their new cage together and give them a few days to adjust before letting them free roam together. Otherwise if Luna gets a scare or they have a go at each other she might run and hide and then it'll be difficult to get her out. Always a 'rule of note' the longer a scared rat stays out the more scared they become.
Now, having said all that, it hasn't always worked 100% I still use different methods based on the rats personalities etc some intros take ages and others very quick with little incident. Some I have used other methods as well and some took months of short visits everyday and eventually I got a different cage completely. Some people put a drop of vanilla essence on the bums above their tails but again, that doesn't always work.
It does sound like they'll be fine, aside from being shy, scared and/or inquisitive, which are normal. Just make sure you've cleaned the cage well and please let us know how it goes
