Can anyone recommend software that will create a nice looking 3-D
scatter-plot (two predictors, one outcome) and display the regression
plane? A free standalone package would be ideal. Does KY-Plot do this?

In R, that facility is provided by the cloud() function from the lattice
package or scatterplot3d() in the scatterplot3d package.

Worked examples at the R Graphics Gallery:

Appreciate the information, but R Graph Gallery displays just don't do it.
For 3 d plots on a flat screen, you need the viewers ability to rotate the
image just like you would rotate a cube in your hand. The viewer should be
able to change backgrounds so as to be able to contrast parts of the plot
and with the reference axis.
