What specific modules are included in Drupal Commerce Kickstart?
Here's the actual makefile that builds the latest version of Commerce Kickstart.

http://cgit.drupalcode.org/commerce_kickstart/tree/drupal-org.make

Within it, you can find every module that is built in. It includes the machine name of the project and the version number used. 

For example, the entry "projects[ctools][version] = 1.9" shows you the machine name ctools, which is the Chaos Tools module, and the version is 1.9. You can look up the modules on drupal.org by substituting the machine name into the following URL: http://drupal.org/project/MACHINENAME.
