I have cygwin under C:/cygwin, and I run NT Emacs.  I'm very happy with this 
setup.  To help get them to work well together, I downloaded cygwin-mount.el 
from <http://www.emacswiki.org/cgi-bin/wiki/cygwin-mount.el>, and I include 
the following in my .emacs file:

(if (equal system-type 'windows-nt)
    (progn
      (if (require 'cygwin-mount nil t)
	  (progn
	    (setq cygwin-mount-cygwin-bin-directory "C:/cygwin/bin")
	    (cygwin-mount-activate)))
      ;; These don't work because of crlf issues?
      ;;(setq shell-file-name "bash")
      ;;(setenv "SHELL" shell-file-name)
      ;;(setq explicit-shell-file-name shell-file-name)
      (setenv "PATH" (concat "C:\\cygwin\\bin;" (getenv "PATH")))
      (setq exec-path (cons "c:/cygwin/bin" exec-path))))

This setup works quite well for me.  However, I never try to run a shell from 
within emacs, so I don't know if that will work correctly.  I seem to remember 
running into crlf issues (as mentioned in the above comments) that I didn't 
bother trying to track down and fix.

If you're using Emacs 21 or older, you might also try:

(setq archive-zip-use-pkzip nil)	; Even on windows, we use zip/unzip

Not sure if this will matter to you, but at least at one time I found this 
useful.  I think this is no longer necessary with NT Emacs 22.3.

And at one time I found the following useful for getting printing to work:

;; Some of this is specific to Agilent Everett Seaway site
(if (equal system-type 'windows-nt)
    (progn
      (setq lpr-command "C:/WINDOWS/system32/lpr.exe") ; Defaulted to dump to 
PRN:
      (setq printer-name "evt0005")		; Defaulted to PRN
      (setq server-name "evt0005")		; Not a system variable
      (setq lpr-switches (list "-S" server-name)) ; Defaulted to ""
      (setq lpr-headers-switches nil)))		; So we can use "pr"
;; This defaulted to 66 lines, didn't fit on page, but may be Everett-specific
(setq lpr-page-header-switches (quote ("-F" "-l59")))

Good luck...
