www.usb.org - you can get the USB spec there and that is the ultimate answer to all the questions. Alternatively you can have a look into the TBDML source code to see how it is implemented. Chances are fairly good that you will be able to adapt the code to do whatever your application needs and hence the wheel will not have to be re-invented

Ansi C. Kernel level programming is very advanced stuff. You will need Windows DDK (Driver Development Kit) which I believe can be obtained for free. However if you do not need something very special than I do not thing that reinventing the driver is the right choice. My choice was the LibUSB driver which comes with source code and is free. See libusb.sourceforge.net and libusb-win32.sourceforge.net. Example of use of this can again be found in the TBDML sources
