We all start somewhere, I had a Chameleon chip for my xbox before I got the Box. Put it in and it came up asking for a BIOS disk????? No body told me about that!
Thats when I found Xbox scene and in over 12 months since modding my first xbox I have never not found a solution by reading the Tuts and this forum.
Use it as a great resource but do your best to search and read first.
Also remember there are no hard and fast rules in modding an xbox everybody has their favorite method, my suggestion is just how I would do it.
