How To Customize What The Fb Share Button Displays?

I have the facebook social buttons for liking and sharing enabled for my products, but I don't like the text its displaying when the button is clicked. For instance, when you click on share, it shows the category and sub categories in the text post on facebook

So if the item name is "Chair", it displays like this on facebook:

Home::Furniture::Living Room:Chair

Can I edit that to not show the categories and sub categories and only the actual item name?

Also some of my products are CD's are when its shared on facebook it should display as

Product Name




But instead displays as:

Track1, Track2, Track3, Track4.

The linebreaks aren't inserted. Is there a way to fix this?
