As you found out, the TextAttr structure is to declare which font you would
like to be the standard font for anything YOU print into that screen.
The problem with doing what you want is that INTUITION does the displaying
of the screen's title bar and menus. The program called SetFont allows one
to set the default system font for various things, including subsequently
created screens' title bar rendering. I'm not sure how it's done, but I 
believe that source is available, so you might find the answer there.

Of course not.

Yes. You can print text in any RastPort. The system allocates one for every
screen and puts it in the screen structure's RastPort field. To get a pointer
to a screen's RastPort do this:
struct RastPort *rp;
rp = &(screen->RastPort);

Now you can use many, many of the system graphics calls to render into your
screen, including Text(). Note that the screen has no layers defined for it,
so if you have windows on your screen, you can render on top of them if you
use the screen's RastPort. If you have windows on your screen and wish to
render behind them, you should open a BORDERLESS, BACKDROP window on your
screen, and render into ITS RastPort.

Hope this helps, and let me know if you need help finding SetFont.
