I occasionally get apps from Experimental, and am currently running Gnome from there, too. I make no special parameters for it at all. Apt won't update from Experimental unless you specifically ask it to. If you have Testing (or Unstable) in your sources list, along with Experimental, and do a dist-upgrade, nothing will come from Experimental. If you want something from Experimental, you you have to do ... aptitude install -t experimental <[i]package-name</i>
Whatever I update from Experimental is strictly manual. I just check Experimental periodically to see if there is a newer version of gnome-core or gnome-utils, and if there is I install it with aptitude.
