Where are the best places to live near Dallas Texas?

My family is moving to Texas. We are white, middle income and want to raise our kids in a good town / neighorhood without alot of crime and gangs etc: and good school districts. We need to be within 35 miles of Baylor University. We plan to rent.

We are looking for a good neighorhood where people are friendly, no cars on the lawn, no strip clubs and all night liquor stores etc. etc.
Which towns and neighorhoods should we look at, and which should we avoid? Thanks for all your help.
