There is now an official government website for the American Recovery and Reinvestment Act (complete with a terrible photo of President Obama):
The USDOE has also unvieled a section on its website to explain the education portion of the Act.
The web resources here provide state-by-state estimates on the various allocations by category, such as Title I.
Speaking of Title I, that may be another area that can help support arts education in the schools. Use varies by state, but in many places Title I has been used to support arts education and ELL, for example.
