You really should get one of two books to get started. Even if you hate books these two gems are great all around referance guides. Those books are 13 Steps to Mentalism By Tony Corinda: http://www.penguinmagic.com/p/1093
And Practical Mental Magic: http://www.penguinmagic.com/p/575
That out of the way there are also some really great DVDs for beginners. Modern Mentalism by Matt Mello: http://www.penguinmagic.com/p/2352
and Luke Jermay's DVD Emotional Intelligence: http://www.penguinmagic.com/p/1703
While E.I. is technically only one routine, the three phase routine blends several fundamental mentalism techniques and can be used as a structured routine to practice cold reading.
