A. No, typically when changing a domain name you do not need to modify any of your content. The only time you need to is if you have any URLs using the full path of the old domain, then the URL (exa: links) would need to be fixed.

A. Yes, when editing a contact if you scroll down there is the option to add new variables. Address is already a variable that exists and doesn't have to be added. Also, city, state, zipcode and country are all variables that exist and are separate from address. So address is just the street address and then city, state, zipcode and country are separate fields/variables.
You can search by these fields and then click the button to email them individually or use the checkmarks to add them to a contact group (which can be a temporary group just for doing the broadcast). Once you've added them to a contact group you can send a broadcast message to the entire contact group at once.
