Is there a way to customize the featured image size just in the blog posts so that it is 500x333? Is there a code I can add to quick CSS?

How many sidebars do you have? Do you want to change the image size on the single post view?
So you are using this Blog layout: http://www.kriesi.at/themes/abundance/blog/
In that case, you'll need to change the image size that gets generated for both the Pages and for Blog posts in your functions.php. Look for:
$avia_config['imgSize']['page'] = array('width'=>690, 'height'=>200); // image for pages and one column portfolio
Change those values to your desired size and then re-save the file. You'll have to regenerate your images for the new function to take effect on anything you have already uploaded. You can use: http://wordpress.org/extend/plugins/regenerate-thumbnails/
