I would like to decrease the width of pinned icons. I already have the small icons set, but there is still a lot of whitespace around the icon that is unnecessary.
I guess ideally I would like the pinned icons to look like quick launch icons in XP.

No, won't work. It only affects the behaviour of active icons, not the inactive ones. My advice: create a new toolbar (e.g. quickstart) and put your desired icons on that and loose the pinned icons.
