Can I change the order in which hook implementation by different modules are called?
Yes, very simply, you need to set the weight of your module to be heavier. There's a few ways you can do this, but if your module is a contrib module being release back to Drupal.org then the best way is to set it in hook_install() with code like:

db_query("UPDATE {system} SET weight = 100 WHERE name = 'MYMODULE'");


Alternatively you can use the Utility module to set module weights from the module page, however this is only for your personal installation.
