The best thing to do, in my opinion, would be to start reading into some technical analysis and charting information either in the form of books (which are all over the place such as amazon, or a simple google search), or other threads like GoomBoo's Journal in the Economy>Economics>Speculation area of the forums. Of course, GoomBoo's journal is more along the side of intro traders, but he still explains the use of charting (and how to get charts that look like his do) very well, boiled down to a simplified approach. Besides the fact that he does a nice job of explaining his methods, he has a lot of nice references to great books that can be read covering many different areas.
Other than that (getting out there and just seeing what turns up on the internet), go ahead and check out some of the charting sites like btccharts.com, or bitcoincharts.com, and the charts area of bitcoinica.com. Btccharts.com is less informative about the information, but exploring bitcoincharts.com was where I began looking into Bitcoin charting. Finally, you may want to look into investopedia.com or another investing site to help improve your investing vocabulary, because after all, bitcoins are just another currency or security that is traded and follows technical analysis to a T (most of the time...)
(An exception would be currently with the introduction of manipulators into the market, hence the ask walls)
