Just to be nitpicky (or something): should that really matter? I've been
doing it as root, and am now successful reading and writing under my userid
(while using no_root_squash)--will I be unsuccessful if if I switch to
root_squash and still do the mount as root? (I presume that during a boot,
mounts are done by root.)

I understand the above, but as stated/implied in the first comment above,
would be surprised/disappointed if mounts during boot did not work properly.

That's helpful. In the other reading I had done I hadn't found anything about
how to masquerade as a different user in NFS--I don't read manpages as often
as I should--it used to be because they seemed like greek to me--now more of
them make sense--I just need to start reading more of them.
