I've removed the bumper, and bolted a tow bar to it using plates that utilize ALL 6 of the bumper bracket bolts. If you just use the front 4, you can easily bend/crack the tabs. As for lights, I bought myself a set of trailer lights, bolted them to a set of magnets and/or clamps. Then I wired it up, wrapped the wires in electrical tape to make it be one cord up to the plug, and it's worked for me so far.
Just make sure you either remove the rear driveshaft and cap the end of the trans/t-case, or leave the shaft in the trans, and securely tie it up under the bed.
