Thanks for the comments so far.

I would like to avoid tile repair. But I do have spare tiles, the
previous owner was a pack rat.

I agree. It's not worth messing with the tile. Just replace the existing
fixture with the same type/style -- meaning 2-handle faucet like you have
now.

Yes, I have an additional shower in the basement, and yes I predict
some downtime. Of course there is no shutoff for the shower, but
then none of the angle stops in the house actually hold anyway, so
all my work is done shut off at the curb.

After you open up the wall behind the shower, buy shutoff valves (I would
suggest ball valves with a waste port such as:
http://www.dongyavalve.com/products/...0valve122.html ). That way, you
can install them first and then continue the job later if needed without
having to turn off water in the whole house.

And, while you have the water off at the street, install a new, non-leaking,
ball valve with a waste port inside where the main water line comes in.
That will eliminate the need to shut off water at the street for any repairs
or leaks inside your home.
