Answer 1

You can use:

getFilesByName(name) Google Documentatin

Then:

setTrashed(trashed)

Answer 2

Sandy posted the correct method (getFilesByName()) for the DriveApp.folder class.

A code sample would look something like this:

function fileChecker(){
  try{
    var folder1id = '';
    var folder2id = '';

    var folder1 = DriveApp.getFolderById(folder1id);
    var folder2 = DriveApp.getFolderById(folder2id);

    //get the files in folder 1
    var files = folder1.getFiles();

    // loop through the files in folder 1
    while(files.hasNext()){

      // get the individual file in folder 1 to process
      var file = files.next(); 

      // check for same name in folder 2
      var files2 = folder2.getFilesByName(file.getName());

      // the code below assumes there is only the potential for a single file
      // in folder 2 with the same name as folder 1
      // otherwise additional processing would need to be handled
      if(files2.hasNext()){ 
        var file2 = files2.next();
        file.setTrashed(true);
        // add the file to folder 1
        folder1.addFile(file2);
        // remove the file from folder 2
        folder2.removeFile(file2);
      }
    }
  }catch(err){
    Logger.log(err.lineNumber + ' - ' + err);
  }
}
