You are comparing different things. All of the 'texlive/2009' entries 
are file locations. As you are using TeX Live 2009, all of the files 
live inside that folder. On the other hand, the lines

   Document Class: article 2007/10/19 v1.4h Standard LaTeX document class
   ----------
   [Loading MPS to PDF converter (version 2006.09.02).]

are version numbers/dates. So the standard article class has not changed 
since 2007, but the file location is

   /usr/local/texlive/2009/texmf-dist/tex/latex/base/article.cls

and for TeX Live 2010 will be

   /usr/local/texlive/2010/texmf-dist/tex/latex/base/article.cls

There is nothing to worry about.
