Someone did it before I could; a grouping of wedding planning spreadsheets! I'm such a nerd and totally would have made something like this -- it is so awesome it is already made! It has sheets for a guest list, vendor contacts, packing list, wedding weekend spreadsheet, day of timeline (morning AND evening).
Maid of Honor: Buy a scrapbook with removable pages, and mail a page to all of the bachelorette's girlfriends. Ask everyone to decorate one side with photos of herself and/or the bride, funny quotes and memories, a letter, mementos of their friendship, etc. On the other side, have them write out their favorite recipe. Wrap it up and give it to her during the party.
