I agree with those recommendations and would add a few more, available free online. 'The Law' by Fredrick Bastiat, 'Complete Liberty' by Wes Bertrand, and 'The Market For Liberty' by the Tannehills. These last two are available here along with 'Healing Our World' by Dr. Mary Ruwart.
Stefan has contributed a great deal to this subject, if you have not read his works from 'On Truth' to 'How (NOT) To Achieve Freedom', I cannot promote them strongly enough. It's great that you found this forum, I feel Mr. Molyneux has created a space for the conversation that will free the world.
Thank you for making the effort to educate yourself, it's always the first step.
