I was told by the a genius bar employee at the apple store that either adapter will work with either machine when my wife and I were in a similar circumstance. The 60W adapter won't be enough to charge the MBP while under a heavy load, but won't hurt it. The macbook won't be damaged by the 85W adapter. The genius also noted that the cinema displays can charge any magsafe Mac without problems.
