You can hide files and folders from gallery, music player and other apps with this - set a password and then files are inaccesible without a password.
You can download a call blocker so only certain numbers are blocked, but you'll probably need root for this - there will be a record of blocked calls and messages, and you can set answering mode, ie. if your boss calls you can put ringing and he'll think you're busy because it will ring normally for him, while you won't even notice he called. Try it and if it complains about superuser or root, see my sig.
If that's not enough, there's also a vault to hide your messages and protect access with a password.
