Does anyone know how to define a custom control to be in a specific group in the toolbox? Is this an attribute I'm supposed to set on the control?

That's done by the installer of most controls by telling vs.net (using the vs.net SDK code) where to put the controls. You could use a toolboxitem object assigned to your control and use the toolboxitemattribute to config some elements, but it's not really helpful.

Thats the only way? Wow, thats too bad I wanted to break my custom GUI controls out into different groups in the toolbox, but I don't want to have to create and run an installer each time I compile them again...

Well, 'installer' as in: when you install a 3rd party component, the installer takes care of adding the components to the right groups. Though I'm sure it's simply calling something inside VS.NET to get this done. So if you download the VS.NET SDK (VSIP), you should be able to make this happen I think.
