A page with '.php' will do just as good as '.shtml' (but avoid duplicates with '.html'). For the '.php' pages it helps if you avoid parameters that looks like sessionID's (like "..../forum.php?ID=1123").

and a page with '.php' will do just as good as '.html'? :)

Josecito, the file extension shouldn't make a difference. Query strings seem to reduce page performance somewhat (though they can still rank well) and Session IDs are usually poison.
