Need help finishing the wiring on my vanity mirror.

[kxjays]

I build a vanity mirror with 14 light bulb sockets that will have 5w led lights on it and need help with the electrical part. My light bulb sockets do not have a ground wire, but the dimmer/switch I bought does contain one. I have attached photos. I also am adding an outlet to the vanity mirror for my phone charger, etc. I bought ground wire in case I needed to add it, but not sure where to add it or if I need to. The power cord also has a ground wire. I have already attached all light bulb sockets together with copper wire, silver to silver and brass to brass. The frame to the mirror is made of wood. I appreciate the help.
