I know where you are coming from here, CK2 can be an arse to get into when you first play it. I found a tutorial on Youtube that helped me here: http://www.youtube.com/user/TekkorGJC
Just go to his playlist and look for the Crusader King 2 tutorial series, its a few months old now but will give you a good grasp of the basics. Hope this helps you enjoy an amazing game! He also does a CK2 let's play series that is part teaching for the first few episodes but they probably won't be that helpful.
