I didn't have any luck using ftp to get your ISOs.  I found them with  
my browser here:
	http://download.fedora.redhat.com/pub/fedora/linux/core/4/ppc/iso/
Same difference I realize.  I downloaded the first disc and the SHA1SUM  
file.  I verified the SHA1 sum
using 'openssl sha1 <path_to.iso>'.  Proceeded through a verified burn  
and booted from it no
problem on an eMac.  Have you really checked the SHA1 sum on the ISOs  
you downloaded?
	As for holding the option key at boot, it's detailed in the  
troubleshooting section of the User Guide that
comes with New World Macs.  It displays all available startup volumes  
(partitions).  The circular arrow on the
left that you noted tells OF to look for startup volumes again (maybe  
you inserted another cd or just plugged
in a firewire or usb drive).  The arrow on the right tells OF to boot  
from the selected volume.  Every startup
volume found will appear as a "large piece of sheet metal, taller than  
wide."  If the volume is on the internal
hard drive, it will show an icon "which make it resemble a 1930-ish  
French automobile seen from the rear."
Startup volumes on CDs will show a CD icon.  You should see a CD icon  
with a little Tux down in the corner
when you've got a FC4 disk you can boot from.
	My final stab in the dark should all of this prove unfruitful would be  
this:
	Hold option and pop in the YDL disks that do boot properly.  See if  
they come up in the menu.  I suspect they won't.
You've probably got corrupt nvram settings.  Reset it using the  
instructions here: http://www.macgeekery.com/node?from=20
The relevant post is: "Enter Open Firmware with CMD-OPT-O-F after a  
restart and then type in reset-nvram then set-defaults and, finally,  
reset-all to restart the computer."

Finally, here's a link detailing a few more of the Mac boot keys:
