My VSIX package uses a bunch of images and third-party dlls, and when compiled the Release folder contains all of that stuff in the raw form. Looks really bad. Is there any way to create a standalone vsix file I could redistribute?
There should also be a .vsix file in the bin\Release folder that contains all the other files. You can rename it to .zip and view the contents in Windows Explorer to inspect it.
When you install that .vsix on a machine, it should also drop all the other 'loose' files you're talking about into the extension install folder.
