     int index = 0;
  while (index < numItems && listItems[index].compareTo(item) != 0)
      index++;
  return ((index-1) < (index));
}

Answer 1

Okay here are all the errors piece by piece.
public boolean greaterFound(Comparable item)
     int index = 0;Well to start with this is not an error per se. But I would just return true if I found a match and false otherwise. There may be some who think that is terrible... I disagree.
  while (index < numItems && listItems[index].compareTo(item) != 0)What is numItems?
That if is shady.
What you are checking for is flat out wrong.
      index++;I'd be returning true here
return ((index-1) < (index));This is just nonsense. As it stands will always return true and invalidates the rest of your code.
