How to configure Crystal Reports 2008 and IIS7 and Windows Server 2008?

Question

I have downloaded and installed the trial for Crystal Reports 2008 on our Windows 2008 server.  I can open Crystal Reports on the server just fine, but I get HTTP 500 errors when I attempt to view a report hosted on that server via the web.
As far as I can tell, the handler mappings in IIS7 are not configured properly, although I confirmed that the Crystal Reports 2008 install did add several handlers.  I read that I must configure the application pool to enable 32-bit applications.  I did that and am still getting the same error.  Documentation seems sparse and I've spent the better part of the day searching the forum here with no luck.  What am I missing?

Don,
Thank you for the quick response!
We will ultimately be using ASPX/C#, but this simple case has a very basic report with no databind, just a single text label that reads "test succeeded" and I'm attempting to access it by direct URL (i.e. "http://192.168.99.21/crystalreportviewers12/test.rpt").  This works on our Windows 2000 server running Crystal Reports 8.
I've also tested with a simple test.aspx file with only the line "Response.Write(System.DateTime.Now.ToString())" and that works just fine.  This file is in the same folder as the test.rpt file.
If I leave the Application Pool set for the "Integrated" managed pipeline mode, I continue to get a rather generic "500 - Internal server error".  If I switch it to "Classic", I get the following error:
Failed to Execute URL.
