well firstly, paranoid android wont preserve the features because it is AOSP (the Google Edition rom is not AOSP, but it still doesnt have the fancy gimmicks of touchwiz) . The features are touchwiz specific. so ROMs that are based off CM10 (AOKP, Paranoid android, PAC rom, Revolt, Avatar, Baked Bean, MIUI, etc) will not have the smart screen features. there are roms on xda that have some if not most of the bloatware already removed. if you want the S-features, you must stay on a stock rom. Deviant Development has pretty much taken over ROM developmemt for the T-mobile S4, and most of their ROMs are tweaked and debloated(this is the term you should be looking for). if there is other apps you want removed, get a file manager that uses root privileges and browse to system/app. but be wary of what the apps are and do. and have a backup of the rom in working condition before you start deleting shit.
