I wouldn't worry about the Mint wrappers damaging the coins, maybe a little toning but that would be about it. Older paper wrappers have a high sulfur content and would start out toning the coins but over time it could turn into corrosion, especially if the rolls were improperly stored(high humidity, heat, etc). As long as your rolls are properly stored, you should have nothing to worry about. Unwrapping them would destroy any potential value from the special Mint wrappers that you paid an extra ~$11/roll for. I am not saying they will be more valuable than a solid roll from a bank, but collector interests in the future could dictate a premium of some sort for those wrappers.
If you wanted to get really fancy, you could order the roll storage boxes from the Mint http://catalog.usmint.gov/webapp/wc...ory_rn=10142
