there is a similar article to this about purely chocolate stout which i'm sure someone will post a link to, but the common consensus is using pure cocoa essence in your brew to get the chocolate flavours.
as for the orange, another common method often used for wheatbeers is steeping orange zest in water for 30mins and then adding that to the brew before fermentation. you can get different flavours from different oranges, some sweeter, others bitter, so you'll have to decide what exactly you're after before embarking.
use the search function on this website and do a google search as well, i'm sure it has been done successfully before with all-grain and extract.
