How to Setup a Wireless Ubuntu Router

I hope this helps others and gives hobbyists a fun project.
Here's the hardware used:
Celeron based PC (755MHz)
512MB RAM
10GB ATA HDD
Realtek 10/100 NIC (2 of them)
There is an integrated NIC on the motherboard, but I couldn't find any drivers that worked.
AtlantisLand I-Fly A02WP54G (which I borrowed from another PC).
A Basic Server Install:
First thing you'll need to complete is a base server install on the PC (don't use LAMP or DNS). From googling, I found out that the wireless card I'm using will work from Ubuntu versions 5.10 (Breezy) and newer.
After the installation of the server is complete, make sure that you configure your repositories to use "Universe".
