Here is an unpleasant truth - there is no up to date tutorial for Nutch. To make it even more interesting, sometimes the tutorial can contradict real behavior of Nutch, because of lately introduced features/bugs. If you find such cases, please try to fix and contribute to the project.
Welcome to the open source world. Though, my recommendations as a person who started with Nutch less then a year ago : 1) If you just need a simple crawl, you are in luck. Simply run crawl script or several steps according to the Nutch crawl tutorial. 2) If it is bit more comlex you start to face problems either with configuration or with bugs. Therefore, first have a look at Nutch List Archive http://nutch.apache.org/mailing_lists.html , if it doesnt work try to figure out yourself, if that doesnt work ask here or at developer list. 3) In most cases, you HAVE to open the code and fix/discover something. Nutch is really complicated system and to understand it properly you can easily spend 2-3 months trying to get the full basic understanding of the system. It gets even worse if you don't know Hadoop. If you dont I do recomend to read "Hadoop. The definitive guide", because, well, Nutch is Hadoop. Here we are, no pain, no gain.

Yes, I did try some of the tutorials actually but they seem to be missing the complete amount of steps required to successfully scrape in nutch.
