How to set Media Box form elements default value?

Not sure about the title part, but you should be able to set some defaults for images using update_option(). You can try adding the following to your functions.php to set the default size to large – you should be able to take it back out after it’s been called once so you’re not updating the option every single time something loads:

update_option('image_default_size','large');
