How do I replace the headphone jack?

I have a set of Sony MDR7506 Professional Studio Headphones with a bent mini plug. I've managed to unscrew the jacket around the plug to expose a red, green, and copper wire. The red wire and green wires are soldered to a short green board extending out of the bottom of the jack assembly. The copper wire appears to be soldered to the metal clamp that connects the headphone jack assembly to the cable.

I'm planning to see if I can find a replacement jack at Radio Shack, but I'm curious if anyone knows if this arrangement of wires is standard and if there's anything I should be aware of before attempting to replace the jack.

Many thanks!

UPDATE: I finally picked up the parts (at Radio Shack) and completed the repair! The big thing that I learned is that the red wire in these Sony headphones corresponds to the ring; the green wire corresponds to the tip. I figured it out by tearing apart the green board at the bottom of the jack to track the wires. And then I checked to make sure right and left were working properly after the soldering was done by listening to the handy sound files at this website: http://www.audiocheck.net/audiotests_ste...
