Formatting Product Listing

Hi - Sorry if this is a repeat question, but I have been searching for hours and can't find the answer to my problem anywhere...
There is a standard category on zen cart called 'All Products' and when selected, the products are formatted with spacing and lines between them - see link: http://www.r e a d y b e d d y g o.co.uk/index.php?main_page=products_all
however, if any of my other categories are selected and you drill down to the products within these categories, the formatting is completely different and all squashed up with no spacing or lines between images/products.
Can someone please tell me how I can fix this problem and get it all looking the same as the 'All Products' pages? I have looked in the Configuration listing for hours and forums/zen cart FAQs and can't find anything. I'm using zen cart version 1.3.8a. I have installed one add on and that was relating to stock & attributes, so completely unrelated to product list formatting. I have put spaces between each letter of my domain name as advised to prevent my site coming up in search engines, so this will obviously need removing for you to see my site.
Any help will be most appreciated! Many thanks!

All product use a different template than product listing. Both pages use tables to display the products. You can adjust margins in CSS for the product listing page or locate tpl_tabular display and adjust the table spacing or padding there. It would require some work to get the product listing to look exactly like all products page.

OK - so formatting the Products in a similar way isn't straight forward then and can't be done from the Admin area? I was wondering if I had missed something, but it seems I need to change some template settings? I think I will probably go and ask my hosting support then to see if they can help me as I won't have a clue! thanks for the reply...

there is a mod available that makes all the "product listing" pages uniform in appearance (product_listing, all_listing, new_listing, specials, featured, etc)

let me see if i can't find it 'round here somewhere..

ahh.. here it is:
