After living with quite a number of large B.W. trees in my 1 1/2 year
old new home, I have decided several need to be removed. They are just
too darn messy, and I'm having some trouble with plants within their
driplines.

Since all are fully leafed out now, and already dropping nuts, I
envision a pretty huge pile of grindings when the tree guys come.

Black walnut lumber is very valuable and you would do better looking for
someone to buy the trees and remove them for you.

If I decide to leave all these grindings on my property somewhere, to
compost into future usable soil enrichment, will these composted
grindings be toxic to other plantS, or are the walnut toxins only
produced while the trees are alive?

You will encounter the same antigrowth toxins from the dead stuff as you
will from the live trees. See above.

Also, I will have a bunch of logs, some maybe over 2' diameter. Would
these be of any value other than making several winter's worth of firewood?

Used mostly for gun stocks and furniture David, very valuable wood. I
brokered a sale of 10,000 board feet a number of years ago and the owner
made out like a bandit. Check around in your area for folks who might be
interested in buying them.
