Hi Benayoun and welcome.
Books are the best idea.
Additionally you might try the 14 days to master hold'em program on
www.TiltedDonkey.com
It is not perfect, but it will make you a better player in 14 days. I would not recommend doing the steps where you deposit money online to play at tilteddonkey. You should be doing a rakeback or deposit bonus if you are going to maximize your initial bankroll. But much of the advice there is pretty sound. It will help with pot odds, and it addresses some of the questions you asked above.
GL and see you at the tables.
