It is clearly obvious that you have read more Mormon doctrine than I have...I have never even seen a Mormon book of scriptures; or whatever it is called.
Where would you like to start?
It helps if you some some basic BIB LE under your belt first, though.
You'll hear a LOT about the BoM - Book of MORMON - but hardly any of the LDS doctrine or practices come from it.
The OTHER lds scriptures are the ones with the 'goodies' in them.
