Hi and welcome to virtual customs,
Ok hope this helps,
1, you need to change the content margins of the log off panel, 0,0,0,0 , change the first 2 sets of numbers , example: 10,10,0,0 that will move left and right, the last 2 sets of numbers are for the up and down position.
2, looks to me like sizing margin is out, adjust the last 2 sets of numbers.
3, Start Menu > Panels > Aero > Top > Programs List > More Programs Tab
and that last one, that looks like sizing margins too, again the last 2 sets of numbers.
