The largest category of Visual Styles/WindowBlinds skins is Vista look-a-likes. The problem with Vista emulation is that Aero glass is hard to duplicate, so it is virtually impossible to get a carbon copy of Vista with Aero turned on. It’s easier if you try duplicating the Vista Basic theme, but everyone wants the glass effects. Visual styles don’t support transparency, so you’re going to need WindowBlinds if you want glass. Styler toolbar is needed for explorer to look similar, and the official wallpapers help. The sidebar has been ported, but it can be buggy. Look at these sites:
JoeJoe.org | The best community/download site for Aerofication.
Thoosje | Thoosje makes some good apps, and his most famous is his sidebar emulator.
Vista Transformation Pack | It’s like Flyakite for Vista
Vista Icontweaker | A Vista icon theme for Icontweaker.
Vista 2.4-2.3 | Widely considered the best Vista skin for WindowBlinds.
Vista Wallpaper | Links to the Vista Wallpapers
