Simple Contact Form not working correctly

Hi, I am having problems with the simple contact form that comes with the package.
http://vmrdesign.com.au/test/Gecko2/#small_conntact_form

1. At the moment the default form collects three pieces of information: Email, subject and message. When the email is sent the subject line of the email is NOT the subject that was input to the form. In every case, the subject in the email received is “Contact from Hot Simple Contact”.

2. I understand it is a very simple form but I think every contact form should at least collect the name and phone number of the sender as well as the email address. The form does not have these fields, even as options. How can I add them? Alternatively, do you have an alternate contact form plugin that I can use?

Thanks
