When we did a similar thing in Denver protesting against Pakistan's Kargil adevnture, we had to get permission for all the slogans before-hand, and the march parth pre-defined.
It is important that you include "Dalai Lama", "Buddha/Buddhism" and "Dharma/Karma" words in your slogans bcs thats what most Americans understand. Make it sound like a protest against an attack on those words.
Best wishes.
:D
