Answer 1

Is it possible to add thumbnails to blog post listings independent of images in a blog post

set the 'featured image' when writing/editing your post; and use the_post_thumbnail() within the loop, in the template.

e.g. if there is no image in the blog post, can I add a thumbnail image?

dependent on a post image, you can check (in your template, in the loop) if the post contains an image, and then output the post thumbnail, for instance with:

if( !strpos(' '.$post->post_content, '<img ') ) the_post_thumbnail();

details depend on your design.

Answer 2

You can use the has_post_thumbnail() conditional tag to check if the post has a thumbnail, if thumbnail was found, display it by calling the the_post_thumbnail() template tag. If there's no thumbnail found, display custom image.

Example:

if( has_post_thumbnail() )
    the_post_thumbnail();
else 
    echo '<img src="' . get_bloginfo( "template_url" ) . '/images/no-thumbnail.png" />';
