The world's most experienced BGP players are in NANOG mailing list. If you go to NANOG site, check the talk list and search for 'tutorial'(http://www.nanog.org/subjects.html) you'll find a few excelent bgp stuff. In one of the tutorial, the author doesn't think a reader should carry on if he/she doesn't config the following first:
no auto
no sync
bgp 200 200 200
My understanding is that by changing the distance of bgp, we can forget the concept of back-door routes.
