Centerboxes Formatting

[WellCool]

Hi all,

I'm trying to fine tune the formatting of my New Products centrebox.

See the attached picture, where the top two boxes are examples of their current layout, and the bottom two boxes show how I'd like them to appear.

The changes are:

Vertically centre all of the images and product titles.
Prevent the product titles 'running into' one another (i.e. add padding between).
Add padding around the perimeter of the border, to prevent the product titles almost touching it.

I've been trying to add padding, margin and alignment settings in tpl_modules_products_new_listing.php but to no avail.

Any help would be greatly appreciated.
Many thanks.
