STO wiki is how I started, learned the basics. Then I used the most usefull, and oldest way to learn : trial and error. You can also use a very good friend of mine, google.
I didn't know at this time, but you can rely on starbase UGC for tutorial, and tips.
Then for very specific problem, not covered by any of this tools, plz feel free to post here, so we can share our knowledge, and try to solve your problem.
