I need a gc-linux hardware shopping list

What hardware do I need to get started with gc-linux?  I have all of the 
computer (Linux/WinXP) and network equipment.  I am mostly concerned 
with the GameCube specific stuff.  Here is a list of what I think I 
need.  What is missing / not needed.
1.) GameCube system
2.) network adaptor
3.) PSO game
3.) PSOloader software (is this open source?)

Also, what documentation exists?  I have the easy stuff like PowerPC 
Arch Manual (Green book), O'Reilly everything Linux, etc.  I am looking 
for information on the GC arch and maybe some speculation on what flavor 
PowerPC that the Gekko is closest to.  I have some low level development 
experience on Mot PPC 750 and IBM 750FX.  Any comments???
