How to remove Adobe from menubar

You would most likely need to use a translucent/transparent background image to accomplish what you're asking. If you know how to make an image 90% transparent then you should be able to experiment and to come up with something similar. Tweaking the UI is art in many ways, however, it's not necessarily a function of the interface creating the effect; the elements that compose it (background color, wallpaper, dock and icons) play a key role.

System Preferences > Desktop & Screen Saver > Translucent menu bar

• One app that I've used to achieve a similar effect is called Nocturne. I'm unsure of it's compatibility with Lion though.

Hold ⌘ and drag it out of the menubar. Also, in the networking system preference, you can often find a show icon in the menu bar preference. I can't recall if this checkbox is easily shown when the hardware is no longer present, but it's an alternative to dragging the icon out directly in some cases.
