NOTICE: This Q&A below is only for directshow sdk.
A: UCMOS, U3CMOS, UHCCD, EXCCD, SCCCD
A: For normal directshow application development, pure directshow programming is sufficient. For advanced directshow application development (such as camera control GUI customization), interfaces in toupcam_dshow.h are available. A how-to-use C++ source code sample toupcamdemodshow.zip is shipped within toupcamsdk.zip as well. There is also a sample program source code amcap.zip (provided by Microsoft) in the samples directory.
A: No. The directshow sdk only support one camera instance, which mean that toupcam.ax always open the "first" camera connected to the computer. If you want open multiple instance simultaneously, please use the native API.
A: Microsoft's MSDN is the most complete reference of DirectShow. You can access it at http://msdn.microsoft.com/en-us/library/dd375454%28v=VS.85%29.aspx

NOTE: Exposure time unit is microsecond.
A: Query the IToupcamStillImage interface.
A: Code example can be found in TCaptureContext::get_framerate function in capture.h and capture.cpp of the toupcamdemodshow sample project.
A: Use the IToupcamSerialNumber interface. Code example can be found in the toupcamdemodshow sample project.
A: Yes, of course. The SDK is DirectShow based and can be easily integrated into your .net applications. See http://directshownet.sourceforge.net/ for more details.
