Category query for oscommerce

I have an OsCommerce store. I need to display the top category and parent category which the item belongs to in the "New products for.." box (includes/modules/[login to view URL])found on the main page. I sell videogames so when you enter my store you find the "New Products for January" box. For instance, in this box you can see a game called "Fifa 09", but I need to show if it is for Wii, PS2 etc and if it is used or new which are my top and parent categories. This is a very low budget project since I think that this is very easy for someone who is familiar with oscommerce / PHP. Please do not bid on this project if you cannot prove you have OSCommerce Experience.
