Answer 1

The Windows SDK (7.1) contains DirectShow sample filter code, including a source filter, which I've successfully used to build source filters for live devices.

If you have the latest Windows SDK installed, it should be here:

C:\Program Files\Microsoft SDKs\Windows\v7.1\Samples\multimedia\directshow\filters\pushsource

Also, MSDN has great reference material on this topic:
