Have a look at this: http://www.amqrp.org/elmer160/lessons/index.html The course was designed back in the 16F84 days, but it gives you a good grounding in the basic principles, getting you a long way over the "initial hump". Unfortunately the development board that went with it is no longer available, but that shouldn't hold you back much - there are lots of others that will do the job.
