Tracking California independent expenditures

I've been trying to track down what kind of independent expenditures are being made in California statewide and proposition contests.  I dug around a bit and found a few sources for this information -- one is the Late Independent Expenditure search tool available in the "Advanced Search" section of the Secretary of State's Cal-Access campaign disclosure web site.  Another source is the Fair Political Practices Commission (FPPC) tracking page.  I'm still looking for good sources of this information, particularly for tracking outside money in federal contests.
