Answer 1

If you wish to position the menu at the center of the screen you must provide the center co-ordinates in ccl
sprite ->setPosition(ccp(size.width/2, size.height/2));

Answer 2

First you get window size...
CGSize Window_size=[[CCDirector sharedDirector]winSize];
Now set CCMenuItem in CCMenu With position...
CCMenuItem *Minus_Menu_item = [CCMenuItemImage itemWithNormalImage:#"ButtonMinus.png" selectedImage:#"ButtonMinus.png" disabledImage:#"ButtonNum1.png" target:self selector:#selector(Minus_Button:)];
Minus_Menu_item.position=ccp(180, 200);
Menu_Minus=[CCMenu menuWithItems:Minus_Menu_item, nil];
Menu_Minus.position = CGPointZero;
[self addChild:Menu_Minus];
