I get emails all the damned time saying things like, "I've just finished my swap, how do I adjust my timing..."
So clearly there's not much to it. On a technical level of 1-4, I'd give it a 2. It's extremely simple and the web has so much damned information about them that you really don't need anyone else. The only thing that concerns me would be tools. If you're planning on doing the swap you WILL need the right tools.
