Swedish greys theme – problem with secondary nav position

Hi – I’ve managed to position the secondary nav (secondary-nav) almost to the center. It appears to be off slightly to the left.

Also, when I view the blog on my iphone the items in the menu have an over state (rounded grey box) which doesn’t lie central over the menu item and seems to be off to the right.

Perhaps the two are connected.

Either way I’d be grateful if anyone could help me get the menu exactly in the center.
