I wouldn't trust the dealer to change the wiper inserts without screwing something up. This is an easy fix and you can handle it without any problems, I am sure.
The only tool you need is a good and sharp pen knife to trim the tape. Other than than, you use a razor blade to remove the tape from the emblem, and a rag with acrisol or goo gone to get the remaining adhesive off the hatch.
After the tape has time to set, you will need to apply a fresh coat of wax to the hatch cause the adhesive remover will remove the wax also.
