The gray patch measures L=46.81, a=(+0.65) , b=(-0.64).Is that about right?

Thats perfect! Less than one a/b unit from neutral...
Maybe it's
just the incandescent lighting that I am using to view the print.

Depending on the inks and paper you are using, there could be a considerable metameric tint caused by the difference between neutral under a D50 light source, and your incandescent lighting...
One thing I still don't
understand is why the soft proof window preview seems to get warmer when I check the
soft proof box to "on". Why would it take a grayscale image and make it look warmer on
screen?

Well, your paper tone is one reason, and your paper whiteners could be another. Adjust the a*/b* values in the "Ref White" box and rebuild your profile, to adjust the softproof tint.
