On a product list page, how far should the items be?

I have the product list page below defined and I'm having trouble figuring out what information should be associated with what.

For example:

• Should the filtering group on the left be closer to the products on the right and further from the title, or at the same distance from both?
• Should the title be at the same distance from the filter and products/filters?

I think is the relationship between things.
Anyway, any suggestions for improvements are also welcome!
