First of all, welcome to fTR. I am quite confident that you will find a plethora of knowledge here that can take your game to many levels above where it currently is.

As others have mentioned, in addition to reading all of the articles and books that you are currently reading you will gain a TON of knowledge just by reading posts in the forums and by posting hands that you feel were tricky and hearing other people's ideas. Doing these two things will allow you to take what you read in books and articles and apply that knowledge to specific situations.

Again, welcome and good luck at the tables.
