I have read NASA's March 2006 article "Solar Storm Warning". It states the solar storm expected in 2012-2013 will be 30%-50% stronger than normal. The US National Academy of Science says they were only able to make these calculations as of 2006. My question is would this be enough to knock out all or some electricity?

That material is out-of-date. The current projection (made in May 2009) reads, "…the next solar cycle will be below average in intensity, with a maximum sunspot number of 90." Of course, that is a projection, and it is subject to revision or being completely wrong.

As for the OP, NASA personnel have expressed their concerns at various times over the ability of infrastructure to weather a major geomagnetic event. Regarding specific steps taken by government or industry, I don't know. I do know that the STEREO project has made early warning much more possible than it was not that long ago, and that's probably the most important thing. Honestly, a Carrington-style event tomorrow might be problematic and very costly, but the catastrophes, doomsdays and civilization-crushing solar flares being "forecasted" by 2012 nuts range from unlikely to impossible.
