Cruise control and front bumber

[Conrod]

Hello Yaris World friends, I just purchased a new 2012 YR hatch auto and very happy with it. I have two questions you may be able to help me with. I would like to put cruise control on it and understand that most of the hardware is in place and I just need the stalk control. Here in down under Toyota spares wont sell you the bits, you have to take to them and shell out $500 plus for them to install. Does any one know where to get genuine cruise control parts.
Q2 . I only had it for a couple of days and backed out of the mates driveway and scraped the bottom of the front bumper You can not see the damage unless you look under but it still hurts and I will proberbly get it repaired. I will avoid bad driveways now but is there anything you can get to protect the bumper underside.

Thanks in advance
