There's a way in Emacs to do everything (well, perhaps except a cup
of coffee ;-).

You want "C-u M-|", I think.  See the doc string of
shell-command-on-region (bound to M-|) for more details.

It sounds like you missed the documentation of c-macro-expand, which
says:

    c-macro-expand is an interactive autoloaded Lisp function in `cmacexp'.
    (c-macro-expand START END SUBST)

    Expand C macros in the region, using the C preprocessor.
    Normally display output in temp buffer, but
    prefix arg means replace the region with it.

Note the last sentence: it means that "C-u M-x c-macro-expand RET"
will replace the marked region with the results of the expansion.

For reindenting, just mark the region and then type "C-M-\".
