Need Centerpieces And MOH Help

I need help. I am getting married in September 2004 and would like help with come creative, but elegant centerpieces. I do not want to use pumpkins, but rather some type of fresh flowers maybe. Any suggestions?

I am also wondering if there is a rule of who walks first down the aisle? I am having three bridesmaids, a matron of honor and a maid of honor. Please let me know. Thanks
