is there a way to not display any results initially until the form has been submitted?
Also, I cant see where I can override the exposed form

You can override the form with hook_form_alter
in a custom module.
I don't believe there is a option in the Views UI to display nothing before selection. In your theme you could check if there is an selection, and hide the results if needed.
As @googletorp mentioned, you can override the expose form using hook_form_alter()
: check out a couple examples in other questions to get an idea of how it works:
To display a blank form unless the user fills out the exposed form, you can use hook_views_query_alter()
in a custom module:
function test_views_query_alter(&$view, &$query) {
$filter_set = FALSE;
foreach ($view->filter as $filter) {
// Check if we've found a filter identifier that is set
if ($filter->options['exposed'] && array_key_exists($filter->options['expose']['identifier'], $_GET)) {
$filter_set = TRUE;
break;
}
}
// If the filter isn't set, add a WHERE clause to the query that
// cannot be TRUE. This ensures the view returns no results.
if (!$filter_set) {
$query->add_where(0, 'FALSE');
}
}
you can set a default filter (between the exposed ones) with a comparison that is always false.
If a filter is made optional in the exposed filter settings, the view should still display the results...
