Does anyone here have solid budget numbers for how much has been spent to-date on the Constellation Program? Especially Ares-I and Orion? Just curious.

I don’t, but I have the impression that Jim Muncy of the Space Frontier Foundation does. I don’t currently have a contact for Muncy, but he should be relatively easy to track down. I make this assumption based on his having numerous long-term contacts on the Hill, NASA, and the aerospace industry.
One caution of course: Jim is a major critic of NASA, and that may color his numbers. He has recently cited a figure of $44 billion being spent by the time of the first full-up system launch, which he suspects won’t be until 2017. If I have time, I will try to track the source where I read him saying that (it may have beeen Simberg’s site, but I’m not sure).

This GAO report provides Constellation budget numbers from 2007 onwards:
http://www.cbo.gov/ftpdocs/98xx/doc9886/11-03-NASA_Letter.pdf
“…Constellation Program’s budget ranges from about $3 billion in 2007 to more than $3.5 billion in 2010…”
So for 2007-2008, we are talking about ~$6B. I don’t think Constellation had a formal budget till 2006. I don’t know how much it was off hand but would guestimate $1.5B range. That would give a total of about $7.5B so far.
This report

gives the following estimates for just Ares I/Orion through first flights:
Ares I: $17B to $20B
Orion capsule: $20B to $29B
I believe that $44B number for the total cost of Ares/Orion first hit the press in this article
