Reset the master password through applescript

Question

I understand that the correct procedure to reset the master password is to delete these two files from the computer:
/Library/Keychains/FileVaultMaster.cer
/Library/Keychains/FileVaultMaster.keychain
The next step is to go into system preferences and click users and groups. The lock has to be unlocked and then the settings button has to be clicked. The text will now say set master password. I can now enter in information in the new popup screen.
I would like to automate this process through applescript. I need some help on navigation of the system preferences. I have looked at turn Airport on and off code through applescript and don't quite understand how to click the settings and unlock buttons.
Here is that code:
tell application "System Preferences"
  activate
end tell
tell application "System Events"
  tell process "System Preferences"
    click menu item "Sharing" of menu "View" of menu bar 1
    delay 2
    tell window "Sharing"
      click checkbox 1 of row 11 of table 1 of scroll area 1 of group 1
      delay 1
      if (exists sheet 1) then
        if (exists button "Turn AirPort On" of sheet 1) then
          click button "Turn AirPort On" of sheet 1
          delay 1
        end if
        click button "Start" of sheet 1
      end if
    end tell
  end tell
end tell

If it's running Mac OS X 10.6.8 or earlier, insert a Mac OS X install DVD, restart with the Option key held down, click on it, and use the Reset Password utility.
If it's running Mac OS X 10.7 or newer, restart with the Command and R keys held down, open the Terminal, and use the resetpassword command:
