So, how would I know if there is a new package in it, other than having to compare it to the previous snapshot? Does the filename (00-index.tar.gz) change?
The filename doesn't change. You could use the RSS feed or the upload log (http://hackage.haskell.org/packages/archive/log), both of which are updated at the same time as the index.
