A general sketch (assumes you have set up separate Apple IDs for your husband and your daughter):
On your daughter's phone:
In Settings > iCloud, tap Delete Account and verify [Will remove all your shared data from this phone.]
In Settings > iCloud, add your daughter's Apple ID, set options (mail, contacts, calendars, etc.) as needed
In Settings > iTunes & App Stores > Apple ID, if you are still signed in, good; otherwise sign in your Apple ID
Set up any other data and settings your daughter needs on her phone. Since she only recently got it, it may not be extensively customized.
Repeat the above with your husband's phone. I gather he has had his longer, so it may be more work getting back to where he was. You may want to wait a while after switching your daughter's phone so you know more about living with the transition.
You should now have three seperate identities for contacts, calendars, iCloud email, FaceTime, iMessages, and the like. One of those identities is also the app/music/video purchasing account on all three.
For extra points (and extra pain), create a new Apple ID for yourself and use the purchasing account for only purchasing. [This is a step I have never taken.]
If you find that you liked some aspects of sharing one calendar account, you can go back and set up one or more shared calendars. Contacts are trickier; I haven't mastered sharing those.
I didn't ask if you also have your Apple ID tied to one or more Macs and how you use them. That may affect the choices you make during the switch of the phones.
Please note that I have not performed the transition I outlined above. I set my wife's first iPhone up with a separate Apple ID and iCloud account I had made for her previously. (Actually, it was part of a MobileMe family pack account back then.)
