1. Fedora installer is smart enough to detect Ubuntu (or whatever else it 
finds). It will overwrite your MBR with its own GRUB and will configure 
it to run Ubuntu as one of the present operating systems.

If this is OK with you, there is no need in any GRUB re-configurations. 

2. If you prefer (this was my case) to keep Ubuntu's GRUB being in 
command, then you would need to take some extra steps.

a. During the installation of Fedora it will ask you, were you would like 
GRUB to be installed. Do not select your MBR but select the partition 
where you would be installing Fedora instead.

b. Then reboot into Ubuntu and edit it's menu.lst file adding a line like 

title		Fedora (or whatever you would like to name this menu item)
root		(hdN,X) (put your numbers here instead of N and X)
chainloader	+1

Then reboot. You'll find Fedora added to the list of presented OSs and 
you would be able to boot either Ubuntu or Fedora now.

As always doing any major change to your box like this make a full backup 
first. In your case I would image the entire drive (I use Clonezilla for 
this - very simple and reliable. Just google for it).
