What part?  

Setting the CYGWIN env var is to just shut a noisy warning from Rtools
off. It does not suggest you should use Cygwin.

The rest seems correct to me.

MSys is not needed, it is just for you convenience. But yes, I place its part
before Cygwin too.

As it stated repeatedly in several places, use the same compiler that R was
built on for Windows to build your add-ons such as Rcpp or RInside code.

If you know what you're doing you can swap other compilers.  One guys
apparently happily plugged in a newer MinGW:

I would not recommend that you start there.  

Keep it simple. Follow the documentation. Things tend to work if you do.
Once you know the ropes, do whatever :)
