It sounds like your very new to poker....like very new....So my suggestion would be not study everything at once but study each section...say working with position and pre-flop hands....study it..work on it a few days or until you feel you've got it down, then move to something else like ranging opponents and reading hands (this one takes awhile and has a lot to do with experiance, so this wouldnt be something id try to tackle right away)...really try to work and understand what your learning..dont just read and be a bot about it...fully understand the info and APPLY IT..and if you dont get it post it and someone around here will answer your question...

FYI: Learn RIGHT AWAY!!!
1) Using/calculating pot odds
2) the power of positiona and applying it correctly
3) Understanding implied odds and reading the board
4) Basic math info on hands like you have a 1 in 8 chance of hitting a set when you have two paired hole cards...info like that

Learn the above first and go from there..if you take the time to do that you should start making some $$$$$ soon...GL..Hope this at least gets you on the right track...
