maybe you stop by in the introduction section too, and get a set of useful starter links.
if you just want to have a look on newer neogamma versions, look here.
it is really up to you what you want to use or update.
i think the #001 can be fixed by updating your cIOS too (if you don't have a modchip installed aswell). have a look on the Error Index (link below)
when you completly want to roundhousekick your wii to be super duper up to date.
use the softmod any wii guide (link below) you will end up perfectly modded with a proper set of nice tools, loading apps, perfect cIOS/IOS set
i like to have my game collection on one harddrive, no need to stand up and switch discs/burning, getting mad on bad burns etc.
if you decide to go on usb loading use the Fat32 guide (link below)
good luck for your next steps
