Billy,
Wiring seems a little heavy. I used 16 gauge for the lights and the battery wiring is 12 gauge.
Depending on what you want, Tractor Supply has a kit to wire everything except the battery line for $25. includes tail and marker lamps and the wiring. Etrailer has several kits from $20 up http://www.etrailer.com/dept-pg-Trailer_Lights-sf-Light_Kit.aspx
If you use car jacks you should probably get ones that go as high as possible. I don't know what those cost but Etrailer has the swing down type for $16 each and they will bolt on. The frame is set up for 4 but I would probably only use 2 in the back. I do that on my standy and it's fine.
