few things in our Oscommerce

I would like to change a few things in our Oscommerce [login to view URL] [login to view URL] new products which we are adding are not displayed in the categories. We can see them in the section "Nowy Produkt" (new products), but they do not show when I click on the category. For example, the first product on the list "nowe produkty" (the t-shirt "Bóg jest ze mną") is only displayed in "nowe produkty" (new products), but it is not displayed in the category. [login to view URL] When I click on the category "koszulki" there are 2 subcategories: "młodzieżowe" and "dla dorosłych". Next to the first category it says that there are 5 products and the second category there are 19. However, when you click on the pages, in the first category 7 products are displayed and in the second category 17 products are displayed. 2. The miniatures are not refreshed in categories. After changing the picture of a product,the miniatures in the categories are not changed and there are old files remaining. I would like to change this. 3. I would like to add a few things to the product display. "Poleć znajomemu", "Zapytaj o produkt" "Cena promocyjna", "Dodatkowe zdjęcia" , etc, just like it is here: [login to view URL] All the necessary mechanisms have already been installed. It is set up on the same engine as in the link above. 4. Changing the font so that it is the same everywhere in the system.
