You can make a custom template for a custom post type. Generally I use the single.php file and duplicate it. Then I rename it to single-{custom-post-type}.php as per Post Type Templates. In your case the template file should look like this single-uslugi.php.
As far as saving the old URLs and fixing things I don’t quite understand what you are looking for. More information about the problem is needed before I can contribute to a solution.
