eddyh, it sounds like you are trying to just show thumbnails and maybe a price on your category pages, is this correct? If so, you need to modify "customer/main/products_t.tpl" you should see the references to "Our price, market price, see details, etc." Comment out what you don't want using "{* what you want to remove *}" and save the file as a different name (personally, I just add "-1, -2, etc" to each edit I make. Then upload using FTP and change the name by removing the -1 and test by reloading the page.

As for changing the number to anything above 3, Lingerieblowout is probably correct about changing the coding. Without looking at it I don't know where.
