I'm needing a few small tweaks to the contact form on this

Hello,
I'm needing a few small tweaks to the contact form on this page:
http://m62.siteground.biz/~contenta/kaivenemore.com/contact/

1) I'm trying to make the form fields {currently white} have no background color so they appear transparent like in the attached picture.

2) Have the input text color be white.

3) Have the submit button background turn to #e1be60 and the text white when it's hovered over.

Thanks in advance,
Casper
