There are some newbies out there who actually spend the time to read how to do everything, and they have successfully moded their Xbox. I'm sure that if you read just as much as them, you'ld be fine too.
Xbox modding is not something that just comes to you, you need to read and find out how to do it and other information. Some people even read for hours and hours to find their answer. If they STILL don't find it, they'll post on X-S. Here at X-S we won't just walk you through every single step, you'll need to figure some stuff out on your own.
EDIT: If you haven't already looked there, the FAQ section should help you a lot
