RMS Levels

I've been working on my mixing and proper mixing levels and started using a template created by member jsaras (his name is Jonas, here's his template http://forum.cakewalk.com/tm.asp?m=843953). According to him, the proper levels are:

-20dB RMS, -6dB Peak RMS before mastering and
-14dB RMS,-10 dB Peak RMS after mastering.

Using Voxengo Span, I'm getting PeakRMS left -8.1 and Peak RMS right -8.4, and RMS -20.9.

Using DFX RMS Buddy, I'm getting pretty much the same thing, -21.45 average RMS.
My Master bus is set to RMS and it gives me a peak of +1.4, which RMS Buddy does as well.

Am I in the ballpark? I still have no idea what I'm doing, but Jonas' template has helped quite a bit with workflow as well as using sends, ect., and of course reading threads for hours from this forum helps as well. Any feedback would be appreciated.
