I recommend Bogleheads Guide To Investing as a good resource for 90% of "normal" investors (the super wealthy need more). The Bogleheads online forum is also helpful and well-moderated.

Podcasts: many, but Motley Fool Money is variably geared toward novice, intermediate, and advanced investors. You can peruse their library and pick topics. They have a daily market update which hits the high points well.
