Our guide is kept current. We recommend you follow it. A link to the Softmod Any Wii guide is in my signature.
As for playing burned games, the system has to be old enough to have the hardware capable of reading those disks. Newer systems won't be able to. We sugguest USB Loading as a substitute. You can store your library on a hard drive and play everything without needing to swap out any disks.
And your first post, talking about yourself and your modding experience, is in exactly the right spot. Others will most likely reply after me with additional links and things for you to read. But I figure that I'd chime in and get you started on the right path.
