WPPA plugin

Hi, I am relatively new to using wordpress and I am using wp photo album as a plugin to display my portfolio. When you use it you have the main page which shows the album when you click the album it displays a thumbnail page then into the slide show or filmstrip. I want to get rid of the middle thumbnail page. It is completely pointless for what I need.

Secondly, Does anyone know a good shopping cart plugin that will work well with wppa+ I was using wp-ultra-simple-paypal-shopping-cart but the Wppa+ plugin is telling me I need to uninstall it

Thanks for any help you can offer!
