GRUB Queries ?!

Hello,
I am posting the following questions here because I need them answered by people who have actually done a lot of work in GRUB. DO NOT GIVE ME GUESS ANSWERS PLEASE. Feel free to redirect me if this is not the right place to ask these questions.

Can I download GRUB separately from GNU GRUB - Obtaining GRUB ? If so why do Linux distributions such as Debian have their own versions of GRUB ? ie. Debian -- Details of package grub-efi-amd64 in squeeze. What is the difference and why are both required ?
Does the recent version of GRUB require Linux configuration files before it can boot Linux ? Is that the reason why every Linux distro has its own version of GRUB ?
If GRUB requires Linux configuration files then how does it boot Windows without similar config files ? And if it is possible to boot an OS like Windows with any extra files in the bootloader why isn't the same thing done for any Linux distro ? wouldn't that make things more streamlined ?
Do all the recent versions of GRUB support EFI booting ?
I have installed Debian on my pc without GRUB thus I can't access it. Can GRUB be installed now manually so that I can dual boot Windows and Debian in EFI mode ?

I am really confused about these basic things. I need to get these things cleared up before I ask further questions in this forum.

grub-reboot

GRUB-REBOOT(8)						  System Administration Utilities					    GRUB-REBOOT(8)

NAME

       grub-reboot - set the default boot entry for GRUB, for the next boot only

SYNOPSIS

       grub-reboot [OPTION] MENU_ENTRY

DESCRIPTION

       Set the default boot menu entry for GRUB, for the next boot only.

       -h, --help
	      print this message and exit

       -V, --version
	      print the version information and exit

       --boot-directory=DIR
	      expect GRUB images under the directory DIR/grub instead of the /boot/grub directory

       MENU_ENTRY is a number, a menu item title or a menu item identifier. Please note that menu items in submenus or sub-submenus require speci-
       fying the submenu components and then the menu item component. The titles should be separated using the greater-than character (>) with	no
       extra  spaces.  Depending on your shell some characters including > may need escaping. More information about this is available in the GRUB
       Manual in the section about the 'default' command.
