Yes.

No. It easy to teach it to understand MSYS path syntax.
This done trough

  file-name-handler-alist

   *Alist of elements (REGEXP . HANDLER) for file names handled
    specially. If a file name matches REGEXP, then all I/O on that
    file is done by calling HANDLER.

in elisp. There are added special patterns:

  ("^/cygdrive/[A-Za-z]/" . cygwin-mount-map-drive-hook-function)
  ("^//[A-Za-z]/" . cygwin-mount-map-drive-hook-function)
  ("^/[^:@]*$\\|^/|/[^/:]+\\(\\'\\|/\\)" . cygwin-mount-name-hook-function)

So if you type C-x C-f (open file command) and enter path /bin/cmd
it open 'E:\bin\msys\bin\cmd' file.

For vim it really need make MSYS build to get it work with MSYS.

With Emacs you can use native build from FSF:

   http://ftp.gnu.org/pub/gnu/emacs/windows/

and with cygwin-mount.el teach Emacs understand MSYS path.
