how to pull the custom setting records in to string 

Would someone be able to help me write a trigger so that when an account address and phone number change, the address and phone number on all contacts change?  In my perfect world, the phone number would only change on the contact IF before the update they were the same number.  Since I am not a code writer other than when I have to be, I am not sure that is even possible.

 

 

Thanks!
