If you want to build Cygwin apps, you'll want to put Rtools later (or not mention it at all), because Rtools is set up to build native Windows binaries, not Cygwin-linked ones. Rtools includes a subset of the Cygwin tools; it's possible that Cygwin has newer versions of some of them, but you don't always want them. In particular, make and tar from Cygwin won't work to build R. See the README.txt file in the Rtools (http://www.murdoch-sutherland.com/Rtools/README.txt) for details.
The other complication with having both Rtools and Cygwin installed is that they both have copies of the Cygwin dlls. You want the latest versions. Rtools has fairly recent ones, but Cygwin's may be newer.
