I have just installed Drupal's Ubercart, and cannot figure out how to place it in one of the main site menus. Also, I want to have the users pay in points that they will gain. Is that feature supported in ubercart or should I turn to a programmer?
First you have to arrange the taxonomy and next you have to install or enable sub catalog module which is a part of ubercart module. Then the catalog module available in your block settings. Put the block on one of your regions. Otherwise, If you want to display your products such new product or specific product category, you have to learn Views module to arrange all of your stuff, choose to display as page and create path and link on your menu.
