Here is an answer to the question about the Adoption Tax Credit.
The current federal adoption tax credit will end on December 31st, 2010, so next year. At that time it will revert to $6,000 for only special needs adoption with the lower (pre 2002) family income limit and tied to expenses.
Last time, the tax credit was going to be like this was starting January 1st, 2002, and the leaders of extending and expanding the adoption tax credit was led by agencies who charge fees and whose families need help paying those fees. There are already a number of bills that will continue the current credit. The person I talked to doesn't expect it to move forward until health care is over. In 2001, the continuation bill was in the Bush tax cuts, and that happened in the summer.
