How to edit head & body for specific Page

I created a custom slider at http://imageslidermaker.com/v2
I love the way it looks in preview and I'd like to add it to my Home Page. It's asking me to insert code into the Head, then insert different code into the Body then Create a CSS file.
I have no clue how to add code to the head and body of a page through WordPress, and if I just add it to the head & footer files in IPower (the file system I use) how will it know to only put it on my home page, and where to put it?
As you can see I'm a noob so simple language to explain this would be helpful :slight_smile:
