关于在expedia上租FOX车的问题？

今天在expedia上组了FOX的14天MUSTANG，PICK UP和DROP OF都在LAX，但有几个问题搞不太明白：


1、FOX上有关保险有两种说明，完全看不懂有什么区别，谁能帮忙解释下：

Rental Liability Protection (RLP) Primary insurance protecting you against claims made by third party for bodily injury and/or property damage sustained while operating the rental vehicle, up to the required financial responsibility limits of the state in which the vehicle is rented. RLP does not cover all situations that may arise while operating a rental vehicle. Cost - USD/12.99 per rental day.

NOTE - In Phoenix, AZ, Denver, CO and Orlando, FL vehicles are supplied with liability coverage that meets state minimums. The renter is financially responsible for all damages not covered under the liability policy including, but not limited to the FOX rental vehicles full value.


Supplemental Liability Protection (SLP) - Provides coverage for 3rd party automobile claims for the difference between the primary liability limits provided under the renters own personal policy and a maximum combined single limit of one million dollars for bodily injury and/or property damage but does not cover all situations that may arise while operating a rental vehicle. Cost - USD/11.99 to USD/12.99 per rental day depending on the rental location.


2、expedia上定了FOX的车之后，竟然只让我输入了个人姓名等个人信息，没有输入信用卡信息等，在确认邮件中也没有说在PICK UP的时候需要带什么东西，是否应该打印确认邮件，实在搞不懂应该怎么办了，请在expedia上定过FOX车的人帮忙给解释下，万分感谢！！！！
