How can I edit Breadcrumb/url of products?

[catchop]

Hello. I'm using 1.6 version.

When searching my products, google only displays them this way

mywebsite.com › shirt ▼
Man's Big Light Blue Shirt - Mywebsite.com
Meta Description

'shirt' is the category of the product 'Man's Big Light Blue Shirt', and its URL is 
mywebsite.com/mans-big-light-blue-shirt

but for better visibility, I want this to be

mywebsite.com › mans-big-light-blue-shirt ▼
Man's Big Light Blue Shirt - Mywebsite.com
Meta Description

or

mywebsite.com › shirt › mans-big-light-blue-shirt ▼
Man's Big Light Blue Shirt - Mywebsite.com
Meta Description

I think I need to modity breadcrumb.tpl in order to do this, and can anyone tell me what to change?

Thank you.
