Fall Wedding Help Needed

I am getting married this fall and am looking for some ideas and was hoping some of you could help me. Our color is plum and silver and we are having an elegant but fallish wedding. Have any of you seen any really neat cakes? I am also looking for a headtable and cake table backdrop, cheap but nice party favors, and a unity candle with fall leaves in it. I am also trying to work color into my bouqet and was wondering if any of you had suggestions. Thanks for all your suggestions - I am starting to get nervous that I don`t have any ides about these items and would appreciate any help!!!
