I am inclined to the same view as @ChrisTenone (including his comment about ignoring me).
With regard to your question 1, if what you have in mind is to write a tutorial that you believe would be useful for other newbies feel free to do so, but keep in mind that there are already many Arduino tutorials on the internet.
One of the risks you run, with a tutorial that is written by a newbie, is recommending "bad habits" such as using delay() or trying to read more characters with Serial.read() than are known to be in the input buffer. That sort of thing will draw a lot of adverse comment.
