[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] laanrobe:
OK, I looked a bit further in the apps manager to see what could be turned off on our Galaxy SIII with stock Android 4.3, specifically in the long list of Samsung apps. I tried to verify each app by searching for it and if it was listed in other lists with 'apps safe to freeze', I just turned it off. Of course every user could have different needs, so this list is not necessarily the right list for everyone. For example, if you are a heavy user of Samsung services, you might want to skip most if not all Samsung apps. Same if you use a lot of AT&T services. For me this list works, since I almost exclusively use Google services. Seeing this list of 70+ apps that provide little or no value to me, I am pretty sure my next phone will be a Nexus...

So here is the extended list, also with the contributions of Capa1970:
