There are a number of good free tutorials on the net, both text and pictures, and video. Do a search and since they're free review a few of them until you get the picture. All derailleur systems are basically the same, so don't sweat whether the tutorials are for your exact system, you just want to get a good understanding of the basics.
Here's one trick that will help you know if it's a limit screw or cable tension problem.
When you can't shift to the end of the range. Forget the levers for a moment and put them in the slack position. Now adjust the limit screws shifting by pulling the bare wire away from the down tube like a bow string. That will allow good adjustment of the limits, and confirm that the derailleur is capable of the shift. Now it's only a matter of setting the cable tension. I do this using the shift form the 2nd sprocket to the third and back, so the limit can't be a factor. Once the 2-3 shift is right all the rest follow, though you might end up making some very tiny fine tuning adjustments.
