CSS Contextual Selectors

I trying to wrap by head around selecting the correct element on the html page within CSS.

In html

<fieldset id="commentFS">
      <label>
            Username
                  <input name="username" id="username"  required="required"
                         title="Supply your username" />
      </label>
      <label>
            Comment <br /> (500 character limit)
            <textarea name="commentBox"  id="commentBox"      maxlength="500"></textarea>      
      </label>            
      <p>
            <input type="submit" value="Submit Comment" />                        
      </p>                              
</fieldset>

If I want to apply the same style rule to the input box and the textarea, do I create my selector as follows:
label input, label textarea {};

if I want to change the background color of the input boxes and the textarea, when they have focus, do I create the selector as follows ?

input:focus, textarea:focus {
      background-color: rgb(225, 225, 240);
}

Is it necessary to prefix both with label?

that is superfluous, just input, textarea {}

yes that's right but no, you don't need the labels. This could also be label *: focus {}
