Cart view page

Oops .... Mistakes,,,,, He it go again.....

Hi,

I wish following related to cart:

1. When (add to cart) is clicked, the user should remain on same page, only product/item should be added/updated in cart. Currently the user is taken to the viewcart page.

2. When cart is viewed a option to resume shopping be available.

I am a beginner in Drupal CMS. Please explain elaborately.

Thanks
