Know-How Exchange : Branding

I am a new marketing manager, fresh out of B-school. I work for a large original equipment manager that wants to now focus on its aftermarket services, the more profitable side of the business. They want to broaden their identity by starting a new branding campaign. Are there any examples of branding plan templates, or marketing communications plans available that I can use as a starting point? I'm sure there is a process to this: customer research, risk analysis of rebranding, looking at the competition, etc., but I am unsure of where to begin. Help please!!
