I forgot to add the ViewPoint readout. For this, all you need is the 
PlotLabel option. (I got this from a Google online sample from Stan 
Wagon's "Mathematica in Action", a great book.)

PlotLabel -> Dynamic[
  StringForm[
   "ViewPoint=``",
   NumberForm[Chop[{
								viewR Cos[viewθ] Sin[viewÏ?],
      			   		viewR Sin[viewθ] Sin[viewÏ?],
      			   	   viewR Cos[viewÏ?]
								}],
							3
						]
   ]
  ]

There's a picture at http://home.comcast.net/~cy56/ViewPoint2.tiff and 
a notebook at http://home.comcast.net/~cy56/ViewPoint2.nb .
