Hi Verbal! I am so sorry I took so long to respond, this message was unfortunately buried so I hope I am not too late in answering your questions.
The boning should go on one side of every seam and several flay steel bones in the front. I prefer to have all my bones go from end to end of the seam, but some people like Rufflebutt prefer to make the bones only go as far down as the waist. Here is her tutorial with pictures, perhaps it will answer more questions.
