function.php & CSS Tweaks

Please go to my Shop > Add a product, and checkout.
Here is where I need help:
1. How to get rid off the whole "You May Also Like..." section on this checkout page? http://recordit.co/BUyMcz8fcj

2. On the next checkout page, How do you turn the * into a red (Required) text? http://recordit.co/tKtcf3841J

THank you!!
