You got Pokertracker, now you need Chessbase!
It is important that you play through master games, especially the classics because they show how to execute plans against less than optimal resistance.
You should replay games by Rubinstein and look for the following key motives:
1. Isolating the d-pawn and winning it
2. Acquiring the bishop pair
3. Acquiring Q+N tandem vs. Q+B
4. Acquiring R+B tandom vs. R+N
Once you know what he is trying to accomplish you see how he is doing it.
If you want to know how to approach a position on expert level, then get this book:

Finally, I see that you got the opening manuals by Dzindzi and Alburt which is usually a good way to start. Nevertheless, there are some conceptional problems with it. The black repertoire especially in the Maroczy (which is the variation most likely to appear in practice) is very drawish and doesn't have much upside against weaker players. The white repertoire on the other hand is very speculative to say at least. They leave out many critical lines and some of their stuff is just simply questionable. While you may be able score some cheapos with these openings, this do not qualify as a sound repertoire. Roman is a great teacher, but this book didn't really impress me.
