Answer 1

You catch the submit event, you count the words in the textarea and only submit if it is high enough. Example:

$('#targetForm').submit(function(event) {
    var text = $("#myTextarea").val();
    text = text.split(" ");
    // check for at least 10 words
    if(text.length < 10){
        // prevent submit
        event.preventDefault();
        return false;
    }
});
