Can I use standard 18/2 SPT-2 wire with this Ceramic (type b bulb) socket?

Hi everyone! The other day I picked up a fixture from the local ReStore. It's a 60 watt (takes a type b bulb,) fixture originally meant to be attached to a ceiling box. I'd like to convert it into a table lamp. I've rewired and built many lamps and swag lights, but never one with this kind of socket, and I've never converted a fixture to a plug-in lamp, so I have some questions about grounding and cord types.
