Try this in your css file.

.sidebar .wpcf7 input[type="text"], .sidebar .wpcf7 input[type=email] {
width:260px;
}

Also, looks like you have some errors on your site. If you use firefox with firebug extention installed, you will see errors showing up in the console log. I just thought I would let you know.
