As far as friendliness goes, if you are starting with chicks you can raise just about any breed to be friendly. It just takes spending time with them, holding them a bit, and getting them used to you. Feeding treats out of your hand is a good way to go about it.
Now, breeds. First off, I advise against having any roosters of any breed. They are unpredictable around children. You say your main desire is getting lots of eggs. In that case, I think black sex links would be a great choice. They lay lots of eggs, are easy to sex so you won't have to worry about getting males, and are large enough to be easy going, in most cases. You could even do a mix of black and red sex links. The red sex links lay even better, are also easy to sex, but are smaller and not quite as calm.
