I would search for tutorials with rich examples, like this one. The essence in windows driver development is to get the picture about layers and IRPs, IRQLs, and also to know terms like filter drivers. If you are looking for example codes, here is my Spodek driver code: sf.net link. You will find there a filter driver (for keyboard, keyb.c), kernel space queue (queue.c) and techniques to hide presence in system. It's a legacy (sys) driver though.
