For the dock features refer here : http://www.stardock.com/products/objectdock/
There is this free version and also ObjectDock Plus.
The differences between it is that ObjectDoct Plus enables you to create multiple docks and also tabs for your dock.
The one i'm using is of course ObjectDock Plus.
On the other hand,Icon packager,well, as it sounds like helps you to change icons.There are lots of choice here that you can download and it ends up the boring look of icons on your operating system!
