1. there are lots of solutions.  I have most of my macros is a separate
library called parenscript-extensions.  If it is a "local" macro, I just
define it in the file it is used.

2. See
one solution.

This is my solution:

(defun compile-site-paren-file (name &optional check-date)
  (let ((inf (merge-pathnames (make-pathname :name name :type "paren")
        (outf (merge-pathnames (make-pathname :name name :type "js")
    (when (and (fad:file-exists-p inf)
               (or (not check-date)
                   (not (fad:file-exists-p outf))
                   (> (file-write-date inf) (file-write-date outf))))
      (with-open-file (in inf :direction :input)
        (with-open-file (out outf :direction :output
                                  :if-exists :supersede
                                  :if-does-not-exist :create)
          (let ((*parenscript-stream* out))
            (ps:ps-compile-stream in))

Note: I use the paren extension for parenscript only files. The library fad
is http://weitz.de/cl-fad/. Though this does treat a whole directory it
could.  I prefer to be more explicit in what I am compiling.
