If you've never owned mice as pets, you should not be breeding them yet. Take 6 months to a year to perfect caring for mice before you breed. (but be aware you should not breed older mice) It will make a big difference in the quality of their lives.
I'd also suggest you do a lot more research into it before you breed. Do you know how long a female mouse stays pregnant? Do you know what to do to prevent cannibalization of the babies? When do you separate the young mice to avoid unwanted litters? Ideally you should know the answers to questions like these before breeding. I'm sure others will have other good websites to refer you to for information.
MUST
-habitat (by this I'm guessing you mean a cage or tub of some sort)
-bedding
-mice
-food (If you're unsure about food, just go buy generic lab block mouse food from a pet store. It will be fine, especially for pet store quality mice. Some people may disagree with me, but making custom food is not something a beginner usually wants to deal with. If you do though, by all means, go for it!)
-water bottle mounted to the side of your enclosure.
-hard object for chewing (I use cardboard tubes, they love to rip them up. You can also get wooden blocks.)
-TONS of attention (of course!)
- A hide (I think you should add this to must. Mice need a place to sleep at night, to stay warm and feel secure.)
Males should not be kept together. There's always a good chance they will fight. If you're buying mice from a pet store, there's no way for you to know how old they are, if they've been exposed to females before, if they were in the same litter, what their temperaments are like etc. I see males with torn up ears and wounds in pet stores that house them together all the time. This is not safe. Males are very territorial and are not usually (there are some rare cases) "friends."
Keeping more than one female together is fine for breeding, and as pets.
There is no way to prevent back to back litters with only one cage available to you. Another concern I have is what are you going to do with the babies if no one can take them? You need to be prepared to keep them ALL. They're your responsibility if you breed them and you can't find homes for them. Your cage or tub will probably only be able to hold 3 females OR 1 male.
Hope this helps you! Feel free to send me a private message if you have more questions and I'd be glad to give you more specifics.
