Default [Q] pinger? newbie questions

I haven't heard anyone ask, can I get notifications and text thru Pinger on watch? Can it be rooted? Also I've heard some say you can't get facebook notifications but then seen a video of a guy rooted his to get that, twitter, and internet. I mostly just want pinger, phone, voxer, fb & twitter and maybe words with friends. Can you and if so point how? Thanks
