This link (first 3 posts) may provide some answers...

http://ubuntu.5.n6.nabble.com/Making-a-first-grub-partition-td1672054.html

Note though some commands need to be 'updated' in v 1.99 eg, from 
--root-directory to --boot-directory, from --set to --set=root etc

To answer specifically your questions above,
o this first grub partition can be in any partition
o mbr is at the first sector of the disk, not the partition
  No need to leave room for it, don't worry about it (unless it's UEFI 
and GPT partitioned)
o You can unpack in an OS partition but not in that 'first grub' 
partition as it does not have an OS
o the 'first grub' does not contain any kernel, hence it is just about 
1.2 MB (yes, 'M', not 'G'). I allocate a whooping 100 MB for it. Format 
as ext2 then.
o GUI?, no, I think.
