I don't have much time to look up references at the moment, but the TARP and other stimulus-related bills enjoyed bipartisan support.
I still disagree with your second assertion. The Tea Party forcing the Republicans to the right happened outside Washington and didn't seem directly related to anything Obama or the Democrats had done.
About the Boehner-Obama moment: while (if I recall correctly) it ultimately led to another budget, in the thick of their negotiations, they would have changed tax law as well. [1] I agree that there are fewer easily memorable moments of bipartisanship after 2010 but I do not agree that the Democratic supermajority (which really only lasted a year, due to Scott Brown's election in Massachusetts) played an important role in promoting obstructionism.
Rather, the Tea Party and the ACA fight provided cover for the Republican leadership to do what they had already been planning (see the Washington Post link from above for an unattributed source who claims the same).
I was incorrect about the reason the Boehner-Obama negotiations began - it was the federal borrowing limit [2]. Reports at the time, and since, suggested that this fight was totally unnecessary, as the all expenditures accounted for by the borrowing limit would already have been approved by Congress.
