Everybody is so confused here. I personally think I got is right in a nutshell:
Decide which server you want to play. Your redeemable will be right there, but don't touch them. If you are not happy with that server, go somewhere else, and they will still be there. If you are not happy with your nation, delete your character and start a new on. Your redeemables will still be there. Don't touch them, and they will be everywhere you go.
Redeem them, and they will be gone on all other servers you went, and you will not get them back.
