Oh Im not sure about the name thing, I guess b/c he is your friend, his name should go first but in some circles its really the 'brides" day so her name goes first everywhere, up to you really - if you are not too close with her then putting her name first might make her appreciate the gift that much more and shows you have lots of respect for her as your friends wife (PS what did their invite say? is her name first on that) .. dunno.. either way it will be beautiful!
