Answer 1

The problem is that you use in both statements !$_GET['page'] when using && operator.

When you use !$_GET['page'] in both cases even if you added !isset($_GET['page'] this condition is checked in $_GET['mode'] is empty.

You simple should probably change your statement from:

if(empty($_GET['mode']) && !$_GET['page']) { 
    include($basepath.'/templates/template.home.php');
}

into

if(empty($_GET['mode']) && !isset($_GET['page'])) { 
    include($basepath.'/templates/template.home.php');
}

In this case simple if $_GET['page'] is not set (and of course mode is empty) you should include homepage template
