currently when i get a sms message it displays a preview of the message in the notification area. is there a setting to change this so it does not do this?
I don't believe there is a a mod for that...well, not with the stock messaging app.
Yes there is indeed. Go into the stock messaging app (don't go into an actual message), then press the menu button (left of the home key), then go to settings, Then under the topic of "Notification Settings," uncheck
Preview Message.
There are other settings here so mess around and adjust to your hearts content.
First thing I did on my GS3 (Note 2 should be the same), was change the background and bubble type, as you can see below
