My general response to any questions like this is, "Never throw anything away."

Until you are COMPLETELY done with any work you'll ever do on your Jeep, you don't know what parts you might need.
If you have storage space, store it until you are DONE.
Then put it up for sale. If the price is right, you can sell anything.
Sometimes the right price is free.

The only limitation on moving parts is shipping. It can be a deal killer on things like a frame or an engine. But there are ways around that too. That's where the forums come into play. Sometimes a guy is making a run that will help connect a seller and buyer. Many of us are willing to transport parts when we're going "there" for another reason.
Don't be afraid to post about any parts you have even if you thing they're really junk. One man's junk is another man's treasure.
