Ok well changing them out yourself is kind of a tough process, as you need to kind of knowing what you are doing. So you would need experience, tools, a FSM and a helper.

I would say take it to a good nissan/infiniti dealer and have them do it. They may charge alot, yes but they do warranty the work and the parts and its the best way to go if you dont have all of the above resources.
