Try the Commitment of Traders Report. It's by no means the grail, but does give a view of what big money is doing. It takes awhile to understand. I am still learning it. Careful on that value investing. Wasn't Monish Pabrai a considered a genius until recently.
Damodaran has some stuff on FA. He has a lot of everything on there. http://pages.stern.nyu.edu/~adamodar/ http://www.investopedia.com/articles/basics/06/financialreporting.asp You could try Graham's book itself - "The Intelligent Investor". It's an old book so the writing style is different. I had a hard time reading it. That's the one Buffett recommends.
forget about it. its not worthwhile. trying to trade on fundamentals is a detriment. look at all of the great value guys funds. many are getting killed. the simple truth is that many or most companies do their books in a way to keep people from figuring out what thay are doing.
I'm primarily a trader, so not the best for advice on value investing, but maybe take a look at Joel Greenblatt's book "The little book that Beats the Market". He has a very interesting take on fundamentals an how to analyse them as a value investor.
For commodities I'd recomend cbot.com,agdayta.com,futuresource.com,barchart.com and one cmegroup.com you can watch an order book. Not very fundamental but it gives you a good idea of what is going on.
