Yes, quoting any part of a command name inhibits alias expansion, since the
quotes remain as part of the word when alias expansion is performed.

Yes.  The output is intended to show how a name would be resolved if used
as a command.  The order is

        alias
        reserved word
        function
        builtin
        command hash table
        PATH search

Posix mode changes this slightly.
