Check out the DVD's from Suarez International if you want to learn how to properly handle an AK. This is a great DVD (I own it) to get started, they also have an advanced DVD.

The controls of the AK are logically placed and work well for a combat rifle. They're big, simple and easy to use. I think the biggest problem people have with the AK is that they try to run them like an AR. They're totally different, and once you accept that and learn how to use it, it all comes together and works quite well.
