There's something wrong with your files. These values are far too high (it will be too quiet). Also, Replaygain should always apply the same values to the MPCs (check the values with the Info of the Winamp plug-in, because there's a minor display error in Replaygain: shows 0.01 dB too much in some cases).
I happen to have this album too, so i encoded it to analyze this problem. Sure 'nuff, everything was fine here.
Here are my Replaygain results:

Album Gain is -8.21 dB for this CD (in reality it's -8.20 dB... i told you about the small display bug in Replaygain.exe). I tagged the files with APE 1.0 tags (in EAC, with MPCencT, see
here).
Maybe you should delete your files and encode from scratch, because something is wrong with them, and i can't tell you what it is.
And as you can see, it all went fine for me.
