How to Switch Actors and BG's?

Hello , I am just learning GS and am having some trouble. I am working with a template and want to switch out the actors and backgrounds, etc with my own original art. I cannot figure out how to do this and still retain the attributes of the original actors. I searched the forum but could not find an answer. If anyone could offer any help, it would be greatly appreciated. Thanks!
