Sorry mate I have been a bit busy lately and only just seen your replies.

The numbers represent the number of pixels for Left, Right, Top, Bottom content margins, if you want to increase the height of the menu edit the the number of pixels for the top content margin

Just make sure you use the same number of pixels on all of the areas I listed except for,

Windows 7 > Start Menu > Basic > PlacesList

Windows 7 > Start Menu > Aero > Top > PlacesList

For both of those they should be about 40 pixels less then the other numbers because of the offset already set for the user picture frame.
