What you are exactly trying to do is not clear.I think you messed up with the structural block here. I am not exactly sure but needed to see the xml file where you have created the block "post".If you have not created the block "post",then you cannot use the code
<reference name="post">
From your code it seems that you are trying to change the template to post.phtml.
If that is the case than just change
<reference name="post">
to <reference name="content">
other part seem fine.
Hope this will help!
