I think you can start with these books:

http://www.mikroe.com/en/books/picbook/picbook.htm
http://www.amqrp.org/elmer160/lessons/index.html

These are for a much smaller microcontroller, and some of the registers and
options called or handled a bit different, but you can find out how to
modify the samples using the data sheet of yours:
http://ww1.microchip.com/downloads/en/DeviceDoc/39631a.pdf

Alternatively you can buy that smaller PIC and play with that one until you
confident and can learn the rest with the 18Fxx one.

Let us know if you stuck on something and could not find in either books.
