I didn't read all of your posts so I don't know if this will help or not, but I know I had to do all of these things before I could get anything to work.
Set up page extensions, the executable paths for each, and the verbs in iis
Extensions: .asax, .ascx, .ashx, .asmx, .aspx, .axd, .config, .cs, .csproj, .licx, .rem, .resources, .resx, .vb, .vbproj, .vsdisco, .webinfo
Executable Path: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll
Verbs: GET,HEAD,POST,DEBUG
Also try: Start - Run - and paste this in C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis -r
After I did all of this I could actually see my work.
