XP users extract to the following folder location: C:\Documents and Settings\All Users\Application Data\CustomPortal\Games\CPGolf2\Templates\Golf

The templates will then be listed in the Template editor as Default xxxxx for each of the basic surface types.  You can edit texture, ball sound, lie name, etc. as needed.  I would highly recommend using the "Save As" option and naming any modified templates to create a new custom template.
