You can't search capital letters in Indesign, but that's easily overcome by using a regular expression. Make sure you have a text frame or an insertionpoint selected, then use the script below. A thread is called a Story in Indesign; parentStory of an insertionpoint or frame gives you the story as an object. Apply the regex to its contents. You process the resulting array (here, 'caps') using Indesign's search/replace.

As to finding out about the object model using the ESTK, see <http://www.oreilly.com/catalog/scriptingindesign/>

Hope this helps.

thread = app.selection[0].parentStory; 
caps = thread.contents.match( /[A-Z]{2,}/g ); 
if( caps != null ) 
   { 
   app.findpreferences = app.changePreferences = null; 
   // change following line to any other capitalization if necessary 
   app.changePreferences.capitalization = Capitalization.smallCaps; 
   for( i = 0; i < caps.length; i++ ) 
      thread.search( caps[i], false, true, 
         caps[i].toLowerCase() ); 
   }
