in the webassist/jq_validation/Cafe.css file
the width for the form labels cant be set on an individual basis in the form builder wizard. you would need to edit the label code manually to add an inline style tag, for example:
<label style="width: 332px;" for="iagree" class="sublabel"> I understand that I am requesting Premiuim Support and I will be charged for this.<span class="requiredIndicator"> *</span></label>
also, where you want the user to chose one item or the other, phone or email, you should be using radio buttons instead of checkboxes.
checkboxes are used where they should be able to chose multiple options.
radio buttons are used when the user should be able to choose only one option.
