 * In the WP Shopping cart I’ve edited the thumnail size to increase its height 
   and width in the dashboard but it seems to result in a “pixilated” low resolution
   image, almost like it enlarged a small bitmap to a larger one. Must I create 
   a thumbnail image of the size I need? Where would I link it to the thumbnail 
   selector in the shopping cart product setup?

 * Your thumbnails should be the same size you have set, or larger. If you have 
   a smaller image, it will be stretched to fit the minimum dimensions you entered.

 * Right Spencer but the product images I upload a fairly large (600x600px). Does
   WP create a permanent small thumbnail image for display or does it dynamically
   reduce the size of the uploaded image to fit the specificed thumbnail size? When
   I increase the thumbnail display size in admin it looses resolution so I’m wondering
   why this happens.

 * Yes. You need to regenerate your thumbnails. [Try this plugin](http://wordpress.org/extend/plugins/regenerate-thumbnails/).
