Quicksilver is a background application, and I would prefer if it didn't show up in the application switcher when I press Command + Tab. Is it possible to hide applications from showing up in the application switcher?
It appears the Finder is also always in the application switcher that I would rather not see.
To achieve a look like on Windows, activate this: Window > Application Frame
The automatic termination feature introduced in 10.7 should already do that, but it only works with some applications and only in some cases. If you for example open Preview, open at least one window in it, close all windows, and focus another application, Preview should be hidden from the Dock and the application switcher. The process is not actually terminated, but there might be some changes in how it is managed.
