Answers to some of your questions about synchronizing contacts between your Moto X and Gmail
How does my Moto X™ back up and restore contacts with Gmail™?
If you set up a Google™ account on your phone, your contacts automatically synchronize with your Gmail account.
If you add contacts to your phone before setting up a Google account, your contacts don't synchronize with Gmail. They save as Phone Only contacts. However, after you set up a Google account on your phone, your Phone Only contacts will synchronize with your Gmail account.
After you've associated your Google account with your phone, anytime you add, import, or transfer a contact, you can choose where to save the contact.
