Questions about customizing listing fields

Hi,

I’ve just started customizing the Responsive Directory theme and I’ve stuck when trying to set the custom listing fields. It would be great if someone could pointing me in the right way:

1) The listing has three default fields (title, description and keywords) that in the “add listing” form appears in the first section (or box). Can these fields be removed, renamed o moved to the second section?

2) I have added some basic custom fields, all of them appear in the second section of the “add listing” form, and in the “details” tab of each one of the view page. Can this behavior be changed? Creating new sections or moving the fields to the first section?

3) The fourth section of the form shows the Google Map to enter the address. Must I to create the custom fields “country”, “state” and “city” or are already created by default in the theme?

thanks very much for your help

Note: When I said “section” I mean each one of the boxes that appears in the “add listing” form (Responsive Directory Theme)
