Need help creating a hook for a plug-in

Hello all. I need help with hooks. I have a plug-in that places a star-rating review system on user-submitted posts in my wordpress blog. Unfortunately, I have to go into the admin panel every time a new post is submitted and select a “bulk apply rating categories” option before the rating table is added to new posts. I need this to happen automatically when a new post is generated. I have the configuration code for the plug-in, and I can see a function where it shows this bulk apply option. However, I have no coding experience so a lot of it looks like a foreign language. Can anyone help me to set up this simple hook, whereby when a new post is created, all of the categories are checked? If you think you can, I’ll send you the config.php file where you can see the code. Thanks very much!
