Sorry, I totally missed this post. To answer your questions:
1. Current version doesn't have the ability to easily add pagination to the matches page. It would require some code changes in the class for the page. It's doable, but I wouldn't recommend changing the inner parts of the plugin.
But version 2.4.0 will have two hooks that you can use in the same way as the example for the ranking in the help file.
2. You can use the [fp-matches] shortcode together with the do_shortcode function of WordPress.
3. For this you would have to write your own function and query on the database. As the plugin does not have anything for this.
