Reading the Developer Docs won't be the best way to learn about hooks and filters.
The Developer Documentation purely documents the available Gravity Forms hooks, filters and provides an example for each. If you don't understand WordPress hook and filter usage it's definitely going to be foreign to you.
As I mentioned in my reply to one of your other forum posts, the CSS Ready Class documentation is much easier to follow because the CSS Ready Classes are a built in feature and the usage simply involves inserting the Ready Class in the appropriate field option.
Customizations via hooks and filters are not so simple to explain because they are customizations and they could be virtually anything you want them to be.
The best way to learn about hooks and filters will be to read tutorials on WordPress hook and filter usage, maybe buy a book on WordPress development and then get your hands dirty playing around with some WordPress hooks and filters for basic things to get a handle on how they work and what they do.
Here are some tutorials that you can check out online:

http://www.nathanrice.net/blog/an-introduction-to-wordpress-action-hooks/
As for books, I can highly recommend this one:
http://www.amazon.com/Professional-WordPress-Plugin-Development-Williams/dp/0470916222
That is a book on WordPress Plugin development but plugins are essentially custom code that make use of WordPress hooks and filters to enhance, customize and add new functionality to WordPress itself. So the concepts are the same.
