When unsure about a project I have alway's gone to the local library and read about it. It's free and if you are still unsure about your skills, then hire an electrician and watch so you get firsthand the do's and dont's. Like what tools you need for the nextjob.
The one crtical thing you need to do is turn off the power to that area before starting any electrical project.An electrical tester will also come in handy.
Good luck with your project.
