It is quite simple, you do not have to know opengl essentials to use cocos2d. cocos2d is quite simple yet awesome!. Just download the cocos2d 0.99.5 and it comes with sample tests. You will be able to find almost all of the things you want to do in a game i.e. animations, touches, moving sprites, particle system etc etc so just go to: http://www.cocos2d-iphone.org/
