Do tons of tsumego. There are a variety of websites and smartphone apps for this.
Play a ton of games. At least 50 9x9 games, then transition into 19x19. Play fast games at first. You don't have the intuition or knowledge to read 25 moves in when you're only 20kyu (ladders might be an exception). I ripped through 30 games in a week and dropped from 9 to 5 stone handicap against gnuGo a while back.
There's a ton of books, but it helps to be cognizant of what you really need. In the early stages "Graded Go Problems for Beginners" is pretty good, as is "The Second Book of Go". Then there are a few titles in the "Elementary Go" series that are quite good. http://senseis.xmp.net/ is a tremendous reading resource.

baduk movies (some free, mostly paid)

Honestly, put in the time. Look at your games, especially your losses. Analyze the bejesus out of them. KGS is quite good for getting others to review your games too.
