i doubt you can get rid of them without root BUT as long as you dont open them they arent going to do anything to the phone either. You shouldnt have to work about them taking up space or anything like that. I do understand the urge to get rid of them though.
Ha!!!! Found a way to deal with them and remove the clutter!!!!
From within the Application view, hit Edit and create a folder. Put all the unwanted apps in that folder. Similar to iOS and BB. So now I've uncluttered and removed all the unwanted icons and the place is much cleaner. They're inside the folder, so the clutter is lessened which is what was driving me to tears.
I don't know if TouchWiz supports it, but some UI's (like GoLauncher) allow you to simply hide apps. However I probably would go with the folder route like you did since I already use them heavily.
