You will need to wait for something like ObjectDock or WindowBlinds for Win8
While I do not recommend a novice (not saying that you are as I have no idea, this is just in general) try using the following, it is up to you.
This will allow you to use custom Visual Styles as they are created. There are not many at the moment and some could (or will most likely) break Windows 8 at this time. They are being developed, but it will be a while before we see more Styles for Win8.
