1. $templatesused must be defined before global.php is included, so that won't work (you can't cache templates via phpinclude).
2. Check out PAPI at vBT and use:

PHP Code:

if (this("showthread'))
{
    doStuff();
} 


...or if you don't want PAPI:

PHP Code:

if (preg_match("/^.*\/showthread\.php$/", $_SERVER['PHP_SELF']))
{
    doStuff();
}
