Hello.
I have seen some white papers on the basics of Biztalk Design but that might not relate to your scenario that well. You can see a full list here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/bts_2004wp/html/90a5261b-a220-41bf-bf7f-fd759239242c.asp
You are welcome to post ideas here on this forum if you think it would help.
Hope this helps.
