Need Help Resticting Phone

I am new to this place. I got my daughter her first Android based phone, and I need to find some apps or something to help me do a few things.

1) I need to restrict calls to contacts only. The older phones I am used to have this feature built in.

2) I need an app that will help me restrict what she can and cannot alter on the phone. I.E., set it where she cannot edit settings, etc.

If anyone knows of anything, please let me know ASAP. Especially about the contact restrictions. Thank you in advance.
