The real meat is in the 1150 amendments, that's mainly what was being amended last week before Reid shot things down. In fact all three cloture votes were about S.AMDT.1150, not S.1348.
But I agree Phil, tracking the amendments to Amendment 1150 is a task. I used to work on this stuff in DC from time to time, but never mastered the trick of decoding some of the legislative formatting.
