Yes. I firmly believe the correct answer would have been immediate significant cuts, with revenue increases through a simplified tax strucure in a year or two, but that isn't possible in the current environment.
I do not, and never have believed that bondholder default was ever a possibility. Since there seems to be no chance of a substantial reduction of deficits, it's almost a certainty that a lowered credit rating will occur. Of course, I'm not so sure that it matters, since I think the markets will generally ignore it. There is no current option to replace the US dollar as the reserve currency, and there really is no other place for that money to go. It may slightly affect interest rates, but then again, it may not.
