[Plugin: Booking Calendar Pro]: Changing info appearing in admin emails

Two questions here:

1. I would like the user to be forced to tick a checkbox to agree to the Terms and Conditions before they are able to submit the booking form. At the moment the form is sent regardless of whether the box is ticked or not.

Is there a way to make it so that the box MUST be ticked before the form can be sent?

2. I have edited the form to include new fields relevant to my organisation. However, the booking email the admin receives still has the default fields. This is an example of the admin email:

You need to approve new reservation
Person detail information:

First Name:
Last Name:
Email:
Phone:
Number of visitors:
Children:
Details:

However, the fields I actually have on the form are:
Full Name
Nationality
Address
Phone
Email
Additional Guest Names
Additional Details
(Check box to agree to Terms and Conditions)

Is it possible to change this so the email actually displays the personal details my form specifies, rather than the default ones?

Any help is greatly appreciated.
