Not with echo and not with other commands that are built into CMD.
Windows programs other than the shell do remove quotes from their
arguments, thus emulating some of the Unixy shell semantics, but CMD
does not.

No.

Just stick '"'.  You don't need these variables when the shells are
separated in the first place.
