Well, so far I've installed the SPB Full Screen Keyboard, and hooked that to the camera button. This is perfect. I can toggle between screen orientation exactly the way I hoped. (And the camera button still takes pictures in the camera application.)

Actually wish the keyboard was a little smaller so I could get a little more text on the screen. The typing window is pretty small. But so far so good. I'll try the other recommendations, but this is exactly the kind of thing I wanted.

Thanks for the help.
