I haven't been a beginner in photoshop for a long time so I can't really say which one would be best for a beginner from personal experience (don't take that the wrong way though, i'm still learning things!).
That having been said, all the tutorials here tend to be very well written and easy to follow. Plus the authors tend to be regularly available, usually posting every day, so if you get stuck on something one of them (or any of the rest of us who have muddled through them) are available to help out with any questions you may have.
There are a few satellite styles that seem to be popular right now, Ascension's rendered cloud basis and pasis' layer styles are the ones I see the most. And a lot of people new to photoshop seem to be getting good results, so that might be a good indication for you
