Windows 7 Need help with some customization problems.

[Zyroh]

Hey everyone, this is my first post here, but I've always been a big customizer and registry hacker. I have gotten to the limit of my experimentation, and I can't seem to figure out some things that I am wanting to do. First, I want to change the scrollbar in windows 7 from the boring default scrollbar, to something a bit more personal. I'm wanting the arrow buttons to be skulls, the thumb to be bones and the track background to be flames. Second, I want to change Windows Glass to be completely clear, so i can see the entire background without any distortion. Third I'm wanting to change the minimize, maximize, and close buttons in the titlebar to be circles. Those 3 are the most predominant customizations that I have yet to figure out, so if anyone could help me I'll be greatly appreciative.
