   You would need to modify a core WordPress file (not advisable) – media.php located in wp-includes

   Just do it like this: http://wordpress.tv/2009/01/05/changing-your-default-media-settings/

   Yes, this function registers new image sizes. To override default sizes you can use in functions.php something like
   

   add_theme_support('post-thumbnails');
   update_option('thumbnail_size_w', 150);
   update_option('thumbnail_size_h', 150);
   update_option('large_size_w', 500);

   You can easily find additional info and examples about this functions.
   Check also set_post_thumbnail_size and similar topic
   And to disable creating default image sizes you can set their H and W to 0 (Settings->Media)

   um.. one more thing, it's right if i want to set the height of image to auto ( to keep the ratio ) just set to 0 or don't set it at all?

   add_image_size( 'my-thumb', 300, 9999 ); and add_image_size( 'my-thumb', 300); do the same - height is auto.
   looks the same with update_option('thumbnail_size_h', 0); if height wasn't overridden - there is a risk to get old thumb H
