Are you using ShopSite to create your store pages or are you creating them in another application?
If you are using ShopSite and you select one of the ShopSite provided templates then the add to cart buttons should be on the page with the product information automatically.
If you are using some other application to create your pages and you want to put add to cart buttons on those pages then you go to Merchandising > Order Anywhere, select the product and click View selected Html or view selected links and copy and paste that information into your store page.
You configure PayPal on the Commerce Setup > Payment screen.
