If you're really serious about going down this road (from which there is no turning back) then the only suggestion is to read the Softmode Any Wii Guide. Read it. Read it again. Read it one more time. Don't skip any part of it that you do not understand. Don't gloss over the acronyms or words that you're not familiar with, but rather, hone in on those. Embrace that which you don't know and learn as much as you can about them. The more you know, the better your chances of having a successful outcome will be.
Put a copy of the Softmod ANY Wii guide in your bathroom.
