You can do everything you want but even as flexible as Connections is with its large number of shortcode options for tweaking, there are limitation what can be done with those shortcode options.

To make the changes you want you need to edit eh card-single.php file, so you would need to know some basic PHP and be comfortable making these changes. The file can be found here:
../wp-content/plugins/connections-tile-plus/

For the image, you would change this:

<?php

$entry->getImage( array(
	'image'    => $atts['image_single'] ,
	'height'   => $atts['image_single_height'] ,
	'width'    => $atts['image_single_width'] ,
	'fallback' => array(
		'type'     => $atts['image_single_fallback'] ,
		'string'   => $atts['str_image']
		)
	)
);

?>

to this:

<?php

$entry->getImage( array(
	'image'    => $atts['image_single'] ,
	'height'   => $atts['image_single_height'] ,
	'width'    => $atts['image_single_width'] ,
	'fallback' => array(
		'type'     => 'none',
		'string'   => $atts['str_image']
		)
	)
);

?>

To add the logo, you would add this where you want the logo to be displayed:

<?php

$entry->getImage( array(
	'image'    => 'logo',
	'height'   => $atts['image_single_height'] ,
	'width'    => $atts['image_single_width'] ,
	'fallback' => array(
		'type'     => 'none',
		'string'   => $atts['str_image']
		)
	)
);

?>

If you edit the card-single.php file, I highly suggest you follow the method outlined in this QuickTip so your changes are update safe.

For PDF upload, that is possible, but very complex. The best way to go would be to create a new extension to handle the PDF upload and store the filename and path to the entry meta.

I hope that helps!
